Electrochemical Oxidative Cyclization: Synthesis of Polysubstituted Pyrrole from Enamines

A conceptually novel method for the preparation of pyrrole is described by electrochemical-oxidation-induced intermolecular annulation via enamines. In a simple undivided cell, based on a sodium acetate-facilitated, polysubstituted pyrrole derivations has been facilely synthesized under external oxidant-free condition. This electrosynthetic approach providing an environmentally benign protocol for C-C bond cross-coupling and oxidative annulation, which features unparalleled broad scope of substrates and practicality.

Automated summary

This novel electrochemical method utilizes enamines for the preparation of pyrrole compounds, providing a simple, efficient, and environmentally friendly approach for organic synthesis.
