Silver‐Mediated Synthesis of 4<i>H</i>‐Benzoxazin‐4‐ones by Intramolecular Decarboxylative <i>O</i>‐Acylation Reactions with α‐Oxocarboxylic Acid

Abstract

The first example of an intramolecular decarboxylative acylation reaction for the synthesis of 4 H ‐benzoxazin‐4‐one derivatives has been described. The silver‐mediated reaction has a broad substrate scope and provides a mild and rapid approach to the corresponding products in high yields.
