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.

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.

A three-component reaction of alkynes, arylzinc chlorides and iodomethanes was found to proceed in the presence of a rhodium catalyst to give high yields of trisubstituted/tetrasubstituted alkenes I [R = 2-MeC6H4, 2-Me-4-MeOC6H3, 2-furyl, etc.; R1 = H, Me; R2 = Me, n-Pr, (CH2)4I, etc.; R3 = Me, n-Pr, (CH2)3OMe, etc.; R2R3 = (CH2)10]. The usual arylzinc chlorides only gave trisubstituted alkenes, generated through a migratory carbozincation-cross-coupling sequence, where 1,4-Rh migration from an alkenyl carbon to an aryl carbon occurred. In contrast, 5-membered heteroarylzinc chlorides only gave the tetrasubstituted alkenes via a carborhodation-cross-coupling pathway without 1,4-migration.

In contrast, the introduction of halogenated substituents onto the aromatic ring of the N-benzylidene alanine Me ester substrate was found to enhance the enantioselectivity of the alkylation with a para-chloro substituent giving optimal results. A new procedure for the preparation of the catalysts which avoids the need for chromatog. on sephadex LH20 is reported, and the optimal catalyst obtained in this way was found to be a cobalt(salen) complex.

The synthesis of open-shell polycyclic hydrocarbons with large diradical characters is challenging because of their high reactivities. Herein, two diindeno-fused corannulene regioisomers DIC-1 and DIC-2, curved fragments of fullerene C104, were synthesized that exhibit open-shell singlet ground states. The incorporation of the curved and non-alternant corannulene moiety within diradical systems leads to significant diradical characters as high as 0.98 for DIC-1 and 0.89 for DIC-2. Such high diradical characters can presumably be ascribed to the re-aromatization of the corannulene π system. Although the DIC compounds have large diradical characters, they display excellent stability under ambient conditions. The half-lives are 37 days for DIC-1 and 6.6 days for DIC-2 in solution This work offers a new design strategy towards diradicaloids with large diradical characters yet maintain high stability.

Radical reactivity of diazaphosphinanes to implement hydrodehalogenations of aryl bromides and their cascade cyclization by hydride transfer was reported to give aromatic hydrocarbons R-H [R = Ph, 2-naphthyl, 4-MeOC6H4, etc.] and dihydro-indene derivatives I [X = NH, O, S]. These reactions featured a broad substrate scope, high efficiency and simplicity of manipulation. The radical reactivity of diazaphosphinanes disclosed here differed from their well-established hydridic reactivity and hence opened a new avenue for diazaphosphinane applications in organic syntheses.

The effect of alkylation on the terminal position of aryl and heteroaryl hydrazines in the Fischer indole synthesis was examined Compared to their unalkylated counterparts, reactions using alkylated s provided indole products with higher yields and faster rates. The reactions can be conducted at lower temperatures and are compatible with acid-sensitive functionality. The terminally alkylated hydrazines were readily prepared by a new two-step sequence and held as stable hydrazinium salts. The mild formation of the salts along with the favorable Fischer indole reaction conditions highlights the potential of this approach in later-stage synthetic use.
