N-Unsubstituted β-Lactams from β-Hydroxy-α-amino Acids. Facile Preparation of Intermediates for Isocephalosporins

A facile method has been devised for the synthesis of N-unsubstituted β-lactams.The cis-azido β-lactam (13) obtained by the reaction of azidoacetyl chloride and the Schiff base (10), derived from cinnamaldehyde and a threonine ester, is subjected to contr
