Synthesis of Thioesters by Simultaneous Activation of Carboxylic Acids and Alcohols Using PPh<sub>3</sub>/NBS with Benzyltriethylammonium Tetrathiomolybdate as the Sulfur Transfer Reagent
A new and simple route for the synthesis of thioesters starting from carboxylicacids and alcohols is reported by usingtetrathiomolybdate as the key sulfurtransferreagent. Triphenylphosphane and N-bromosuccinimide were used for the activation of the carboxylicacid and alcohol in the same pot followed by the transfer of sulfur from tetrathiomolybdate. Thioesters were obtained in good to moderate
This article described the thioesterification of carboxylic acids with thiols through the activation of sulfonyl fluoride (SO2F2). The presented one-pot two-step protocol was compatible with aryl/alkyl carboxylic acid including drug molecules.
