The present invention relates generally to compounds that inhibit serine proteases. In particular it is directed to novel heterocyclic compounds, or a stereoisomer or pharmaceutically acceptable salt, solvate, or prodrug form thereof, which are useful as selective inhibitors of serine protease enzymes of the coagulation cascade; for example thrombin, factor VIIa, factor Xa, factor XIa, factor IXa, and/or plasma kallikrein. In particular, it relates to compounds that are factor VIIa inhibitors. This invention also relates to pharmaceutical compositions comprising these compounds and methods of using the same.
Chemoselective acylation of benzimidazoles with phenylacetic acids under different Cu catalysts to give fused five-membered N-heterocycles or tertiary amides

日期:——
bond formation via a copper-catalyzed aerobic oxidative decarboxylative tandem protocol was realized. The phenylacetic acids which contain ortho-X (X = F or Br) on the aromatic ring will render a fused five-membered heterocycle via a tandem aromatic nucleophilic substitution and aerobic oxidative decarboxylative acylation at the C(sp2)–H bond of benzimidazoles under the Cu(OAc)2/K2CO3/BF3·Et2O catalytic
通过铜催化的好氧氧化脱羧串联方案实现了C–N键的形成。在芳环上含有邻-X(X = F或Br)的苯乙酸将通过串联芳族亲核取代和苯并咪唑的C(sp 2)-H键上的好氧氧化脱羧酰化反应,形成稠合的五元杂环在Cu(OAc)2 / K 2 CO 3 / BF 3 ·Et 2 O催化体系下,以CuBr为催化剂,吡啶为碱,发生N-酰化反应,得到叔酰胺。

Synthon
carbohydrate has been identified as an environmentally benign C2 synthon in the preparation of synthetically useful 2-hydroxymethylbenzimidazole derivatives by coupling with 1,2-phenylenediamines. The pivotal features of this method include metal-free conditions, short time, good functional group tolerance, gram scale feasibility and the synthesis of benzimidazole fused 1,4-oxazine.
