indium Lewis acid catalysis, a nitrogen atom of N‐unsubstituted pyrroles was replaced with a nitrogen atom of primary amines, thereby producing N‐aryl‐ and N‐alkylpyrroles. This system formally introducing such carbon frameworks to the pyrrole nitrogen atom shows unique selectivity: only the H−N(pyrrolyl) unit undergoes the N‐arylation and N‐alkylation even in the coexistence of a similar H−N(indolyl)

aromaticity transfer coupling reaction between phenols and pyrrolidines or indolines to generate the corresponding N-cyclohexyl pyrroles or indoles. In this transformation, the aromaticity of phenols is formally passed on to the pyrrolidine or indoline units. Substituted phenols thus can serve as latent cyclohexyl equivalents for the fast construction of various N-cyclohexyl pyrroles and indoles.
