Abstract
Abstract The efficient cyclization reactions of the N -methanesulfonyl or N -ethoxycarbonyl derivatives of 2-ethynylanilines, functionalized on the benzene ring and/or the acetylene terminal into indoles catalyzed by either Cu(OTf) 2 or Cu(OAc) 2 are accomplished. The application of this reaction to the tandem cyclization reaction is also described.
