A simple one-step procedure furnishing regioselectively functionalized imidazo[1,2-a]pyridines (2) by a novel condensation reaction of 1-phenylacetylimidazole (1) with acetylenic dicarboxylic esters is described; the structure of one of the products (2a) has been determined by X-ray crystallography.
描述了一种通过1-苯基乙酰基咪唑(1)与炔属二羧酸酯的新型缩合反应提供区域选择性官能化的咪唑并[1,2- a ]吡啶(2)的简单步骤。产物(2a)之一的结构已经通过X射线晶体学确定。

Functionalized 7H-pyrrolo[1,2-a]imidazoles (2) are obtained directly by a novel double transacylation reaction of 1-acylimidazoles (1) with dimethyl acetylenedicarboxylate (DMAD); the structure of one of the products (2b) has been determined by X-ray crystallography.
功能化的7 H-吡咯并[1,2- a ]咪唑(2)是通过1-酰基咪唑(1)与乙炔二甲酸二甲酯(DMAD)的新型双酰基转移反应直接获得的;产物(2b)之一的结构已经通过X射线晶体学确定。
