Abstract

2-(Substd.-1-azetidinyl)-3-oxo esters are prepd. by reacting (a) a beta-lactam and a di-oxo-ester in inert solvent; treating the prod. with thionyl-chloride in the presence of an acid scavenger and reducing: or (b) reacting a beta-lactam with 2-azido-3-oxo-ester in the presence of RH2(OAc)4 catalyst; or (c) by hydrolysis
