Copper-catalyzed (4+3)-cycloaddition of 4-indolylcarbinols with aziridines: stereoselective synthesis of azepinoindoles†
Abstract
Copper(I)-catalyzed (4+3)-cycloaddition of 4-indolylcarbinols with aziridines has been accomplished to furnish azepinoindoles. The chirality transfer, substrate scope, functional group tolerance, natural product modification and tandem C–C/C–N bond formation are the important practical features.
