Cyclohexanecarboxylic acid chloride synthesis

Thiol esters have recently found broad applications in organic synthesis. Two methods for their preparation from acid chlorides and acids are described in the preparation of 2-METHYLPROPANE-2-THIOL ESTERS OF CYCLOHEXANECARBOXYLIC ACID AND CHOLIC ACID. Conversion of the former thiol ester to the corresponding O-t-butyl ester illustrates a general method for the preparation of O-ESTERS FROM THE CORRESPONDING THIOL ESTERS.
