biological activities of the γ-lactamanalogues (-25), (-25) and (26) of carbapenicillanicacids are described. The strategy employed for the synthesis of effected construction of a γ-lactam onto a preformed azetidine, followed by direct amination of the lactam enolate (20) with diphenylphosphinoyl-hydroxylamine. X-ray crystallographic studies demonstrated that the analogues bore a strong morphological
