Propylphosphonic Anhydride (T3P®)‐ Mediated Efficient Synthesis of Substituted 2‐Amino Phenoxazinones

Abstract

An efficient synthesis of substituted 2‐amino phenoxazinones was described using T3P® via oxidative cross coupling of commercially available 2‐amino phenols. The synthesis is a transition metal free, enzyme free and a non‐photo chemical reaction involving shorter reaction times with moderate to good yields.
