The reactions of exocyclic alpha,beta-unsaturated gamma-lactones with NsONHCO(2)Et and CaO produce N-(ethoxycarbonyl) spiroaziridino gamma-lactones. By reaction with acetic acid these products give ring opening reaction and acetylated N-protected alpha-amino gamma-butyrolactones are obtained. The ring opening reaction is quantitative and highly regioselective. (C) 2003 Elsevier Science Ltd. All rights reserved.
