Iridium-catalyzed regio- and enantioselective allylic esterification of secondary allylic alcohols with carboxylic acids.

We report herein an iridium-catalyzed asymmetric allylic esterification of racemic secondary allylic alcohols using free carboxylic acids as nucleophiles under mild conditions with broad functional group tolerance, exhibiting excellent regio- and enantioselectivity .
