The cyclodehydration of benzyloxycarbonylamino-acids by successive treatment with acid chloride-forming reagents and triethylamine has been shown to give 2-benzyloxyoxazol-5(4H)-ones, not N-benzyloxycarbonylaziridinones as reported previously. The 2-benzyloxyoxazol-5(4H)-ones, which are the first 2-alkoxyoxazol-5(4H)-ones to be described, are more easily attacked by nucleophiles at position 5 and less
