An efficient solution phase protocol for the synthesis of 2-(N-acylamino)benzimidazoles is reported. The 2-(N-acylamino)benzimidazole ring system was assembled using S_NAr reactions, nitro group reduction, acylthiourea formation and cyclization with EDC. The acyl protected 2-aminobenzimidazole derivatives were obtained in high yield and purity without purification of intermediates or final products. This reaction sequence eliminates the use of highly toxic cyanogen bromide, a reagent commonly used to prepare the 2-aminobenzimidazole ring system.

Fowles, Gerald W. A. published the artcileDonor properties of simple ethers. II. Complexes of manganese(II), iron(II), cobalt(II) and nickel(II) halides with tetrahydrofuran and 1,2-dimethoxyethane, Name: Cobalt(II) dibromo(1,2-dimethoxyethane), the publication is Journal of Inorganic and Nuclear Chemistry (1969), 31(10), 3119-31, database is CAplus.

The reactions of several dihalides of Mn(II), Fe(II), Co(II), Ni(II), cu (II), and Cd(II), and Fe(III) chloride with tetrahydrofuran and 1,2-dimethoxyethane have been investigated and the following complexes prepared: MCl2.1.5-C4H8O (M = Mn, Fe, or Co), CoX2.C4H8O (X = Br or I), NiCl2.C4H8O.EtOH, MX2.C4H10O2 (M = Mn, Fe, Co, Ni, or Cd and X = Cl, Br, or I), FeCl3.C4H10O2, and 2CuCl2.C4H10O2. The structures of several of these complexes have been deduced from a study of their electronic spectra, far-ir spectra, and room temperature magnetic properties. However, the magnetic moments of several of these complexes (e.g. pseudotetrahedral CoX2.-C4H10O2) are unusual in that they exhibit marked temperature dependence, although the ground state formally is an orbital singlet. The tetrahydrofuran derivatives MCl2.1.5C4H8O are of unusual stoichiometry, and while it is suggested that these products are a 1:1 mixture of tetrahedral CoCl2.2C4H8O and octahedral CoCl2.C4H8O their structure remains in some doubt.

The synthesis and biol. evaluation of a series of 12,13-aziridinyl epothilone B analogs is described. These compounds were accessed by a practical, general process that involved a 12,13-olefinic Me ketone as a starting material obtained by ozonolytic cleavage of epothilone B followed by tungsten-induced deoxygenation of the epoxide moiety. The attachment of the aziridine structural motif was achieved by application of the Ess-Kurti-Falck aziridination, while the heterocyclic side chains were introduced via stereoselective phosphonate-based olefinations. In order to ensure high (E) selectivities for the latter reaction for electron-rich heterocycles, it became necessary to develop and apply an unprecedented modification of the venerable Horner-Wadsworth-Emmons reaction, employing 2-fluoroethoxyphosphonates that may prove to be of general value in organic synthesis. These studies resulted in the discovery of some of the most potent epothilones reported to date. Equipped with functional groups to accommodate modern drug delivery technologies, some of these compounds exhibited picomolar potencies that qualify them as payloads for antibody drug conjugates (ADCs), while a number of them revealed impressive activities against drug resistant human cancer cells, making them desirable for potential medical applications.

Hydrobrominating RCH:CR¹CO₂H (R = Me, Ph, R¹ = H; R = H, R¹ = Me) with HBr in AcOOH gave 57-83% yields of the corresponding RCHBrCHR¹CO₂H, which reacted with SOCl₂ to give the acid chlorides and then with H₂O₂ in pyridine to give the corresponding (RCHBrCHR¹CO)₂O₂ (I) in ≤75% yield. I underwent thermolysis at 80° or UV photolysis in C₆H₆ or PhMe to give complex mixtures via rearrangement of the initially formed primary radicals to secondary ones via a 1,2-shift of the Br atom.

Marine biofouling plagues all maritime industries at vast economic and environmental cost. Previous and most current methods to control biofouling have employed highly persistent toxins and heavy metals, including tin, copper, and zinc. These toxic methods are resulting in unacceptable environmental harm and are coming under immense regulatory pressure. Eco-friendly alternatives are urgently required to effectively mitigate the neg. consequence of biofouling without causing collateral harm. Amphiphilic micropeptides have recently been shown to exhibit excellent broad-spectrum antifouling activity, with a non-toxic mode of action and innate biodegradability. The present work focused on incorporating the pharmacophore derived from amphiphilic micropeptides into a 2,5-diketopiperazine (DKP) scaffold. This privileged structure is present in a vast number of natural products, including marine natural product antifoulants, and provides advantages of synthetic accessibility and adaptability. A novel route to sym. tetrasubstituted DKPs was developed and a library of amphiphilic 2,5-DKPs were subsequently synthesized. These biodegradable compounds were demonstrated to be potent marine antifoulants displaying broad-spectrum activity in the low micromolar range against a range of common marine fouling organisms. The outcome of planned coating and field trials will dictate the future development of the lead compounds

Retinoic acid receptor-related orphan receptor C (RORc, RORγ, or NR1F3) is a nuclear receptor that plays a major role in the production of interleukin (IL)-17. Considerable efforts have been directed toward the discovery of selective RORc inverse agonists as potential treatments of inflammatory diseases such as psoriasis and rheumatoid arthritis. Using the previously reported tertiary sulfonamide as a starting point, the authors engineered structural modifications that significantly improved human and rat metabolic stabilities while maintaining a potent and highly selective RORc inverse agonist profile. The most advanced δ-sultam compound I possessed favorable RORc cellular potency with 75-fold selectivity for RORc over other ROR family members and >200-fold selectivity over 25 addnl. nuclear receptors in a cell assay panel. The favorable potency, selectivity, in vitro ADME properties, in vivo PK, and dose-dependent inhibition of IL-17 in a PK/PD model support the evaluation of I in preclin. studies.

A new three-component reductive arylation of amides with stable reactants (iPrOH and arylboronate esters), making use of a 2-pyridinyl (Py) directing group, is described. The N-Py-amide substrates are readily prepared from carboxylic acids and PyNH₂, and the resulting N-Py-1-arylalkanamine reaction products are easily transformed into the corresponding chlorides by substitution of the HN-Py group with HCl. The 1-aryl-1-chloroalkane products allow substitution and cross-coupling reactions. Therefore, a general protocol for the transformation of carboxylic acids into a variety of functionalities is obtained. The Py-NH₂ byproduct can be recycled.
