Abstract

A Cu/Bpin system promoted cyclization for the synthesis of 1-difluoroalkylated isoquinolines with vinyl isocyanides and bromodifluoroacetic derivatives in moderate to good yields was reported. This method provided a mild and efficient pathway for the construction of diverse 1-difluoroalkylated isoquinolines via a proposed tandem radical cyclization process.
