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。
