Kinetic Resolution of Secondary Alcohols by NHC-Catalyzed Oxidative Esterification
Publication History
Publication Date:
06 May 2011 (online)

Abstract
Kinetic resolution of racemic secondary alcohols by oxidative esterification using carbene catalysis is described. Good to moderate selectivity has been achieved. N-Heterocyclic carbenes (NHCs) were systematically varied and several aldehydes were included in this study as acyl donors. As an oxidant, a readily available bisquinone-type system was used.
Key words
carbene catalysis - kinetic resolution - oxidative esterification - secondary alcohols - acylazolium ions
