资源简介：
A gold-catalyzed cascade reaction of conjugated diynamides has been developed. In this way, a series of sulfone-containing pyrrolo[2,1-a]isoquinolines featuring the core structural motifs of lamellarin alkaloids were prepared atom economically. Mechanistic studies including DFT calculations uncovered a consecutive 1,2-migration of the sulfonyl group for the formation of a pyrrole ring.
