N-benzoyl amino acids 1a–g react with excess oxalyl chloride at room temperature followed by addition of alcohols to afford 4-substituted 2-phenyloxazole-5-carboxylates 3a–g.
A direct β-acyloxylation of enamine compounds has been achieved by using iodosobenzene (PhIO) as an oxidant to realize the intermolecular oxidative C(sp2)-O bond formation between enamines and various carboxylic acids, including N-protected amino acids. The transformation tolerates a wide range of functional groups and furnishes a variety of β-acyloxy enamines that can be conveniently converted to
