Process for the conversion of primary and secondary alcohols to their corresponding thiols and thiol esters

摘要

Disclosed is a mild, efficient, stereo-selective process for a one step conversion of primary and secondary alcohols to their corresponding thiol ester and thiol derivatives with inversion of configuration. The process comprises the reaction of the alcohol in question (4), the thiolacid of choice (5) in the presence of adduct 3; the resulting thiol ester 6 may be converted to the free thiol 7 by hydrolysis or reductive methods: <IMAGE> +TR <IMAGE>
