A Cu-catalyzed [3+2]-type condensation reaction of oxime acetates and dialkyl acetylenedicarboxylates that provides highly substituted pyrroles under aerobic conditions is described. The newly formed pyrroles are easily employed for further transformations to prepare pyrrolo[2,1-a]isoquinoline skeletons.
描述了一种在有氧条件下,铜催化的肟乙酸酯和二烷基炔二羧酸酯的[3+2]型缩合反应,该反应可高效合成高度取代的吡咯。新生成的吡咯很容易用于进一步转化,以制备吡咯[2,1-a]异喹啉骨架结构。
