PIDA-Mediated Oxidative C−C Bond Formation: Novel Synthesis of Indoles from<i>N</i>-Aryl Enamines

Abstract

A variety of functionalized indoles were synthesized from N-aryl enamines via PIDA-mediated oxidative carbon-carbon bond formation. The features of the present reaction include facilitative preparation of substrates 2, good functional group tolerance, and mild reaction conditions without transition metals.
