We describe an unprecedented Pd(OCOCF3)2-catalyzed cascade process for the synthesis of highly functionalized 1,2,3,5-tetrasubstituted pyrroles with high efficiency. Unlike documented methods relying on preformed enamines and active halogenated terminal alkenes, the process employs simple 2-alkenal-dicarbonyls and primary amines in ‘one-pot’.
我们描述了一种前所未有的Pd(OCOCF3)2催化级联过程,用于高效合成高度官能化的1,2,3,5-四取代吡咯。与依赖预形成的烯胺和活性卤代末端烯烃的已知方法不同,该过程采用简单的2-烯醛二羰基化合物和一级胺在“一锅法”中进行。
