摘要

2-Arylindoles were prepared by a sequential reaction of Ag-catalyzed α-addition–Pd- catalyzed C–H bond functionalization of tetrazoles with bromoalkynes. A stereocontrolled Ag- catalyzed α-addition reaction of tetrazoles with bromoalkynes underwent smoothly to generate (Z)-N-(2-bromo-1-vinyl)-N-arylcyanamides, which were subsequently converted into 2-arylindoles through an intramolecular cyclization by Pd-catalyzed direct C–H bond ...
