A series of novel 1-substituted-2-aryl imidazoles (SAI) were designed and synthesized based on our previously reported ABI (2-Aryl-4-Benzoyl Imidazole) analogs and on the structure of combretastatin A-4 (CA-4). These compounds showed potent antiproliferative activities against six human cancer cell lines with IC50 values in nano molar range. Among them, compound 3X exhibited the best anticancer activity with an average IC50 value of ?100 nM. The compound maintains the mechanism of action by inhibiting tubulin polymerization, thus causing cell arrest at G2/M phase and apoptosis. In vivo efficacy studies indicated that 3X was highly effective in suppressing tumor growth in a MDA-MB-468 xenograft model of nude mouse with a TGI (Tumor Growth Suppression) of 77% at 60 mg/kg without causing significant toxicity. In addition, 3X displayed significantly better water solubility (36.70 mug/mL) than CA-4 (2.83 mug/mL). Molecular modeling study indicated that 3X binds well to the colchicine binding site in tubulin. Our results suggest that the novel SAI analogs deserve further investigation as potential anticancer agents.

Haloaroylmethylidenephosphoranes 3 can be subjected to Pd(o) mediated C-C coupling reactions to yield diaryl-, arylhetaryl-, dihetaryl, arylethenylaryl/hetaryl- and arylethynylaryl/hetaryl-carbonylmethylidenephosphoranes 4-9. Suzuki-Kumada reactions can also be run in a one-step procedure from (haloaroylmethyl)triphenylphosphonium bromides 2. Compounds 4-9 are air-stable phosphoranes which undergo formal Wittig-olefination reactions with aldehydes 10 under benzoic acid catalysis. C-C coupling reaction and Wittig olefination can also be performed in a one-step procedure. Preliminary experiments have been performed to carry out the synthesis on a solid support. Applications to the chain elongation and functionalisation of the chain terminus in a C-7 substituted estra-1,3,5(10)-triene 14 and a C-16 substituted estra-1,3,5(10),6-tetraene 12 are shown.

A kinetic study of the reversible deprotonation of benzofuran-3(2H)-one (3H-O) and benzothiophene-3(2H)-one (3H-S) by amines and hydroxide ion in water at 25 C is reported. The respective conjugate bases, 3–O and 3–S, represent benzofuran and benzothiophene derivatives, respectively, and thus are aromatic. The main question addressed in this paper is whether this aromaticity has the effect of enhancing or lowering intrinsic barriers to proton transfer. These intrinsic barriers were either determined from Bronsted plots for the reactions with amines or calculated on the basis of the Marcus equation for the reaction with OH-; they were found to be lower for the more highly aromatic benzothiophene derivative, indicating that aromaticity lowers the intrinsic barrier. It is shown that the reduction in the intrinsic barrier is not an artifact of other factors such as inductive, steric, resonance, polarizability, and pi-donor effects, although these factors affect the intrinsic barriers in a major way. Our results imply that aromatic stabilization of the transition state is ahead of proton transfer; this contrasts with simple resonance effects, which typically lag behind proton transfer at the transition state, thereby increasing intrinsic barriers.

A strategy for the selective phosphonation of benzofuran and benzothiophene with trialkyl phosphites was developed. In these reactions, the C?H phosphonation of benzofurans or benzothiophenes at the C2 or C3 position with trialkyl phosphites was successfully achieved without directing groups by using a copper catalyst. Additionally, the C5 phosphonation of furan was successful under the same conditions.

Quality Control of 7-Chloro-1-benzothiophene-2-carboxylic acid, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects.

The present invention relates to a process for the preparation of an amide from a carboxylic acid chloride and an organic molecule comprising both a primary amine group and a tertiary amine group, wherein the nitrogen atom of the tertiary amine group is comprised in a non-aromatic heterocycle and wherein the amide bond forms selectively with the primary amine group, comprising the step of reacting the carboxylic acid chloride with an organic molecule comprising both the primary amine group and the tertiary amine group, in the presence of imidazole. This is particularly useful in the preparation of amides from quinuclidin-3-amine, such as for the preparation of encenicline ((R) -7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide) from 7-chloro-benzo[b]thiophene-2-carboxylic acid chloride and (R)- quinuclidin-3-amine in the presence of imidazole. Encenicline is a nicotinic acetylcholine receptor agonist useful as a neuromodulator for the treatment of e.g. cognitive impairment, schizophrenia and Alzheimer’s disease.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 90407-16-2 is helpful to your research.
