摘要：
A general cascade hydroazidation and alkyne-azide 1,3-dipolar cycloaddition of diynes using silver catalysis is reported. A wide variety of diynes participated in the reaction with trimethylsilyl azide (TMS-N-3) in the presence of H2O, affording the corresponding 1,5-fused-1,2,3-triazoles in good-to-excellent yields. This unprecedented protocol is operationally simple with a broad substrate scope, good functional group tolerance, and high reaction efficiency, thus providing easy access to various fused 1,2,3-triazoles.
