摘要

Synthetic utility of the 2-oxazolone moiety as an excellent new leaving group is described. Based on such a function of the heterocycles, diphenyl 2-oxo-3-oxazolinylphosphonate [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 carboxylic acids The 3-acyl-2-oxazolides also serve as versatile reactive agents for ...
