sequence that affords either cyclic β-amidoamine products via direct functionalization or linear hydroxybisamide products via a ringopening pathway. The reaction pathway was dependent on the nature of the N-acyl activating group, with carbamate groups favoring direct isocyanide addition to the N-acyliminium ion intermediate and the benzoyl activating group favoring the ring opening–functionalization

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
