Skeletal diversity: The reactions of alkynoic acids (A, common type of substrates) with various scaffold‐building agents (B) under gold catalysis produce a series of multifunctional polyheterocyclic structures (see scheme). The approach enables the preparation of compound libraries with high skeletal diversity.
Efficient Synthesis of Naturally Occurring Skeleton 5-7-6 Tricyclic Pyrrolo[2,1-c][1,4]benzodiazepin-5-one and Its Derivatives via Cationic π-Cyclization¹
