One‐Pot Electro‐Oxidative Annulation Reactions: Synthesis of Polysubstituted Pyrroles from Anilines and Alkynoates

Abstract

A synthetic method of polysubstituted pyrroles has been established by electro‐oxidative intermolecular annulation of easily available materials, anilines and alkynoates. In an undivided cell, alkynoates and aniline converted smoothly into desired products under external oxidant‐free and mild conditions, mechanism verification experiments indicating that in situ formed enamines are crucial intermediates for the transformation.
