Yee, Ying K.; Bernstein, Peter R.; Adams, Edward J.; Brown, Frederick J.; Cronk, Laura A.; Hebbel, Kevin C.; Vacek, Edward P.; Krell, Robert D.; Snyder, David W. published the artcile< A novel series of selective leukotriene antagonists: exploration and optimization of the acidic region in 1,6-disubstituted indoles and indazoles>, Name: Methyl 4-(bromomethyl)-3-fluorobenzoate, the main research area is leukotriene antagonistic MSBAR indole indazole preparation; antiasthmatic indole indazole preparation.

A systematic structure-activity exploration of the carboxylic acid region in a series of indole- or indazole-derived leukotriene antagonists I [e.g., R = Me(CH2)3CHEt, X = CH, N, R1 = CO2H] led to several discoveries. Use of the 3-methoxy-p-tolyl fragment (illustrated in I) for connecting the indole and the acidic site provides the most potent carboxylic acids I (R = CO2H) tetrazoles I (R1 = tetraacyl) and aryl sulfonimides, e.g I (R = PhSO2NHCO). The aryl sulfonimides are 5-500 times more potent (in vitro and/or in vivo) than the corresponding carboxylic acids. The o-tolyl sulfonimides such as I (R = cyclohexylmethyl, X = N, R1 = 2-MeC6H4SO2NHCO) show greater oral potency than the Ph sulfonimides at a given level of in vitro activity. Acidic sulfone derivatives e.g., I [R = cyclopentylmethyl; X = CH, N; R1 = PhSO2CH(CO2Me)]-(Nu = CH(CO2CH3)SO2Ph) mimic the activity of the acidic imides.

Thompson, H. E.; Swanson, Carl P.; Norman, A. G. published the artcile< New growth-regulating compounds. I. Summary of growth-inhibitory activities of some organic compounds as determined by three tests>, Product Details of C7H4BrNO4, the main research area is .

Growth-regulating substances were prepared and subjected to 3 tests. In each a common reference material, (2,4-dichlorophenoxy)acetic acid (I), was employed and the results of any test were expressed as a percentage of the inhibition produced concurrently by I. The primary test, Test A (Corn Germination Test), involved the determination of inhibition of elongation of the primary root of germinating corn. Corn grains were germinated at 27° in Petri dishes containing 20 mL. of an aqueous solution of the compound to be tested at a concentration of 10 p.p.m. After 4 days of growth the length of the primary root of each plant was measured. Inhibition of growth was determined by subtracting the average length of the primary roots of the treated seeds from that of the control seeds, expressed in percentage. In Test B (Kidney-Bean Single-Droplet Water Test) kidney beans were placed in pots containing 1 lb. soil. After 7-10 days each plant was treated with 0.02 mL. of an aqueous solution containing 200 p.p.m. (4 γ) of the compound to be tested and 0.5% of Carbowax 1500. Treatment was applied to the upper surface of one of the primary leaves at a point along the midrib approx. one-eighth in. from the point of attachment of the blade and petiole. On the 10th day after treatment the fresh weight of that portion of each plant above the second node was determined Controls untreated and also treated with I were included in each test. Test C (Kidney-Bean Single-Droplet Oil Test) was essentially the same as Test B but 0.01 mL. of solution was applied containing 5γ in oil of the compound to be tested. Tri-Bu phosphate, at a concentration of 0.2%, was used as a co-solvent for compounds not directly soluble or miscible with oil. The introduction of I could be accomplished only in this way. Close numerical agreement was not necessarily expected between the 3 tests. The degree of inhibition produced by I in Tests B and C at different times of the year was not wholly identical and was affected by rate of growth. Test A was the most reproducible and formed the primary basis for detection of inhibitory activity and was reliable in separating those compounds that possess a high inhibitory activity for most broad-leaved plants from those with little or no activity at the same concentration Satisfactory agreement was found between Tests A and B with discrepancies in the direction of a lower activity by Test B. Variation between replications was greatest in Test C but the results were satisfactory in separating active inhibitors from those with low activity. Compounds showing high activity are promising for use as herbicides. The compounds tested have been classified into groups according to activity and the results under 3 tests reported. The following, as Group I, are compounds possessing 80% or more of the activity of I in Test A: (2-bromo-4-chlorophenoxy)acetic acid; Bu (2,4,5-trichlorophenoxy) acetate; (2-chloro-4-bromophenoxy)acetic acid; NH4 4-chlorocinnamate; α(4-chlorophenoxy)acetamide; (3-chlorophenoxy)acetic acid; 4-isomer; α-(2,4-dichlorophenoxy)acetamide; 2-(2,4-dichlorophenoxyacetamido)-1-butanol; Na 4-(2,4-dichlorophenoxyacetamido)-2,5-dichlorobenzenesulfonate; 2-(2,4-dichlorophenoxyacetamido)-2-ethyl-1,3-propanediol; 2-(2,4-dichlorophenoxyacetamido)-2-(hydroxymethyl)-1,3-propanediol; 2-(2,4-dichlorophenoxyacetamido)-2-methyl-1,3-propanediol; 2-(2,4-dichlorophenoxyacetamido)-1-naphthalenesulfonic acid; 8-(2,4-dichlorophenoxyacetamido)-1-naphthalenesulfonic acid; 8-(2,4-dichlorophenoxyacetamido)-1-naphthol-3,6-disulfonic acid; (3,4-dichlorophenoxy)acetic acid; 2,5-isomer; (2,4-dichlorophenoxy)acetic anhydride; α-(2,4-dichlorophenoxy)-4-sulfoacetanilide; (2,4-dichlorophenoxy)acetohydroxamic acid; (2,4-dichlorophenoxy) acetyl chloride; (2,4-dichlorophenoxyacetyl)guanidine; N-(2,4-dichlorophenoxyacetyl)urea; α-(2,4-dichlorophenoxy)butyric acid; 2-diethylaminoethyl (2,4-dichlorophenoxy)acetate; 2-diethylaminoethyl (2,4,5-trichlorophenoxy)acetate; 2,2-dimethyl-1,3-dioxolan-4-ylmethyl (2-methyl-4-chlorophenoxy)acetate; 1,4-bis(2,4,5-trichlorophenoxyacetamido)benzene; 1,3-isomer; Et (2,4-dichlorophenoxy)-acetate; Et (2-methyl-4-chlorophenoxy) acetate; Et 2-(2-methyl-4-chlorophenoxy) heptanoate; 2-hydroxyethyl (2,4-dichlorophenoxy)acetate; (2-iodo-4-chlorophenoxy)acetic acid; (2-methyl-4-bromophenoxy)acetic acid; (2-methyl-4-chlorophenoxy)acetamide; N-methyl-α-(4-chlorophenoxy)acetamide; 4-(2-methyl-4-chlorophenoxyacetamido)benzenesulfonic acid; 2-(2-methyl-4-chlorophenoxyacetamido)-6,8-naphthalenedisulfonic acid; 2-(2-methyl-4-chlorophenoxyacetamido)-1-naphthalenesulfonic acid; 8-(2-methyl-4-chlorophenoxyacetamido)-1-naphthalenesulfonic acid; 7-(2-methyl-4-chlorophenoxyacetamido)-1-naphthol-3,6-disulfonic acid; (2-methyl-4-chlorophenoxy)acetic acid; (2-methyl-6-chlorophenoxy)acetic acid; (2-methyl4-chlorophenoxy)acetic anhydride; (2-methyl-4-chlorophenoxy)acetyl chloride; (2-methyl-4-fluorophenoxy)acetic acid; N-methyl-α-(2,4,5-trichlorophenoxy)acetamide; 2-nitro-2-methylpropyl (2,4-dichlorophenoxy)acetate; 2-nitro-2-methylpropyl (2-methyl-4-chlorophenoxy)acetate; Ph chloroacetate; Ph (2-methyl-4-chlorophenoxy)acetate; iso-Pr (2-methyl-4-chlorophenoxy)acetate; 2-(2,4,5-trichlorophenoxyacetamido)-2-(hydroxymethyl)-1,3-propanediol; α-(2,4,5-trichlorophenoxy)-N,N-bis(2-hydroxyethyl)acetamide; (2,4,5-trichlorophenoxy)acetic piperidide; α-(2,4,5-trichlorophenoxy)-3-chloroacetanilide; α-(2,4,5-trichlorophenoxy)-2,4-dimethylacetanilide; α-(2,4,5-trichlorophenoxy)-4-ethoxyacetanilide; α-(2,4,5-trichlorophenoxy)-4-methylacetanilide; α-(2,4,5-trichlorophenoxy)-2,4,6-trichloroacetanilide; [3-(trifluoromethyl)phenoxy] acetic acid; N-[tris(hydroxymethyl)methyl]-N-{2-hydroxy-3-[tris(hydroxymethyl)methylamino]-propyl}-α-(2,4-dichlorophenoxy)acetamide-HCl.

A novel strategy for the direct carboxyl transfer involving a decarboxylative A3 reaction of α-keto acids, primary amines, and alkynes has been developed under a Cu(I)/Cu(II) binary catalysis system. This multicomponent reaction provides a facile and efficient approach for the production of a diverse range of 2-oxazolidinones in moderate to excellent yields through a one-pot CO2 elimination-fixation procedure. The conciseness of the “”CO2 recycling”” process makes this ideal synthesis superior over classical CO2 utilization.

A high-yielding and practical method for the synthesis of phenols from electron-deficient haloarenes and heteroarenes has been developed. The products are formed from acetohydroxamic acid as the hydroxide source via a novel SNAr reaction/Lossen rearrangement sequence. Notably, these reactions employ inexpensive and air-stable reagents, require no special handling, occur under mildly basic conditions, and form products in high yields in the presence of electrophilic and protic functionality. The utility of this methodol. is demonstrated by the high-yielding hydroxylation of two base-sensitive complex substrates.

A general copper-catalyzed carbonylative cross-coupling between amines and alkyl iodides was reported to form amides RC(O)NR1R2 [R = Cy, i-Pr, CH(Et)2, etc.; R1 = H, Me, R2 = n-hexyl, CH2Bn, t-Bu, etc.]. Using a simple combination of catalytic amounts of copper(I) chloride and N,N,N’;N””,N””-pentamethyldiethylenetriamine in the presence of sodium hydroxide under carbon monoxide pressure, a broad range of alkyl iodides and amines can be efficiently coupled to the corresponding amides that are obtained in good to excellent yields. Notable features of this process were the first one relying on a base metal catalyst, includeed the availability and low cost of the catalytic system, its successful use with primary, secondary, tertiary alkyl iodides and all classes of amines with no or limited competing nucleophilic substitution without CO incorporation as well as its efficiency with complex alkyl iodides and amines. Mechanistic studies demonstrated that a radical pathway is operative and the key role of CO.

A convenient photocatalyst-free method for the synthesis of redox-active 1,2-dihydro-3H-indazol-3-one derivatives I (R = benzyl, thiophen-2-ylmethyl, cyclopropylmethyl, iso-Pr, etc.; R1 = H, Br, 3-methylphenyl, 4-methoxyphenyl, naphth-1-yl, furan-3-yl, thiophen-3-yl; R2 = H, Cl) from (2-nitroaryl)methanols 2-O2N-4-R1-5-R2C6H2CH2OH and amines RNH2 was developed. The reaction proceeded efficiently at room temperature by irradiation of UV light under CO2 atmosphere (1.0 atm, flow) without any photocatalysts or additives. This mild, operationally simple method shows wide functional tolerance. The carbamate formed in situ from CO2 and amine is proposed to be the key of this reaction. Some of these compounds synthesized by the present method were found to exhibit high anticancer activities, which can lower the viability of cancerous cell lines such as HeLa, MCF-7 and U87.

Shi, Yusheng; Zhang, Tiexin; Jiang, Xiao-Ming; Xu, Gang; He, Cheng; Duan, Chunying published the artcile< Synergistic photoredox and copper catalysis by diode-like coordination polymer with twisted and polar copper-dye conjugation>, HPLC of Formula: 16426-64-5, the main research area is copper catalysis diode coordination polymer polar dye conjugation.

Synergistic photoredox and copper catalysis confers new synthetic possibilities in the pharmaceutical field, but is seriously affected by the consumptive fluorescence quenching of Cu(II). By decorating bulky auxiliaries into a photoreductive triphenylamine-based ligand to twist the conjugation between the triphenylamine-based ligand and the polar Cu(II)-carboxylate node in the coordination polymer, we report a heterogeneous approach to directly confront this inherent problem. The twisted and polar Cu(II)-dye conjunction endows the coordination polymer with diode-like photoelectronic behaviors, which hampers the inter- and intramol. photoinduced electron transfer from the triphenylamine-moiety to the Cu(II) site and permits reversed-directional ground-state electronic conductivity, rectifying the productive loop circuit for synergising photoredox and copper catalysis in pharmaceutically valuable decarboxylative C(sp3)-heteroatom couplings. The well-retained Cu(II) sites during photoirradiation exhibit unique inner-spheric modulation effects, which endow the couplings with adaptability to different types of nucleophiles and radical precursors under concise reaction conditions, and distinguish the multi-olefinic moieties of biointeresting steride derivatives in their late-stage trifluoromethylation-chloration difunctionalisation.

This study reported a straightforward heterogeneous catalytic (Al-MCM-41) approach to synthesize benzimidazoles I [R = n-Pr, cyclohexyl, Ph, etc.; R1 = H, 5-Me, 5,6-di-Cl, etc.; R2 = H, Bn, CH2CH2Ph] and quinoxalines II [R3 = H, 6-Me, 6-Br, etc.; R4 = H, 4-MeC6H4, 4-ClC6H4, etc.] from primary amines under solvent-free conditions. The Al-MCM-41 catalyst was prepared using a hydrothermal method and characterized by various anal. techniques. The probability and limitations of the catalytic methodol. were presented with various substrates. The catalytic method grants an attractive route to a wide variety of benzimidazole and quinoxaline moieties with good to excellent yields.
