Directing-group-assisted copper-catalyzed oxidative esterification of phenols with aldehydes.

Abstract

A directing-group-assisted copper-catalyzed oxidative esterification of phenols with aldehydes using TBHP as an oxidant was described. This methodology which showed the advantages of base, ligand free, short routes and functional group tolerance could be used as an alternative protocol for the classical esterification reactions.
