A cross‐dehydrogenative coupling reaction of indolizines with electron‐deficient alkenes for the synthesis of 3‐alkenyl‐substituted indolizines has been reported. The reaction takes place at the 3‐position selectively through palladium‐catalyzed CH activation, following a Heck‐type cross‐coupling reaction under mild and ligand‐free conditions. Furthermore, the reaction mechanism of the PdII/Pd0 catalytic
据报道,吲哚嗪与缺乏电子的烯烃发生交叉脱氢偶联反应,可合成3-烯基取代的吲哚嗪。在温和且无配体的条件下发生Heck型交叉偶联反应后,该反应通过钯催化的CH活化选择性地在3位发生。此外,还通过1 H NMR光谱证实了Pd II / Pd 0催化途径的反应机理。

A new class of chymase inhibitor featuring a benzimidazolone core with an acid side chain and a P-1 hydrophobic moiety is described. Incubation of the lead compound with GSH resulted in the formation of a GSH conjugate on the benzothiophene P-1 moiety. Replacement of the benzothiophene with different heterocyclic systems such as indoles and benzoisothiazole is feasible. Among the P-1 replacements, benzoisothiazole prevents the formation of GSH conjugate and an in silico analysis of oxidative potentials agreed with the experimental outcome. (C) 2011 Elsevier Ltd.
