A facile and direct preparation of thiol esters from carboxylic acids and thiols using diphenyl 2-oxo-3-oxazolinylphosphonate in the presence of triethylamine is described.
sphonate [DPPOx] has been newly introduced as a carboxyl-activating reagent which permits a facile direct preparation of 3-acyl-2-oxazolones and amides including peptides from a wide variety of carboxylicacids The 3-acyl-2-oxazolides also serve as versatile reactive agents for highlychemoselective acyl-transfer to the nucleophilic species such as amines, alcohols and thiols, providing convenient
