Facileconversion of alcohols to thioalcohols via thiolesters is described. The synthetic scheme involves (i) preparation of thiolesters (5) by the reaction of ethanethioate anion with 2-alkyloxypyridinium salts (3), formed from 1-methyl-2-fluoropyridinium salt (1) and alcohols, and (ii) subsequent reduction of 5 to thioalcohols. A clean inversion of configuration is noted.
