摘要
A silver(I)- and base-mediated formal [4+3] cycloaddition reaction of in situ generated 1,2-diaza-1,3-dienes with in situ formed C,N-cyclic azomethine imines has been developed. This protocol provided an efficient method for the synthesis of biologically important 1,2,4,5-tetrazepine derivatives with a wild substrate scope and excellent functional group tolerance in moderate to excellent yields.
