Direct C–H functionalization of tetrahydro-γ-carbolines at the α-position†
Abstract
The direct C–H functionalization of tetrahydro-γ-carbolines (THγCs) at the α-position has been presented. This mild and simple strategy allows coupling of THγCs with various anilines and indoles with satisfactory to excellent yields. This two-step/one-pot method could be applied to synthesize complex compounds and is suitable for the C–H functionalization of similar biologically active structures.
