Synthesis using aromatic homolytic substitution—recent advances

Abstract

This critical review aims at presenting recent developments in intramolecular aromatic homolytic substitution which has become one of the common methodologies in modern synthesis. The application of Bu₃SnH-mediated cyclisations have proved especially useful. The critical review illustrates the mechanistic considerations required for planning synthetic applications and a wide range of synthetic protocols and natural product syntheses are shown. The latest evidence for the mechanisms involved in aromatic homolytic substitution are presented. (152 references).
