Abstract

Abstract The use of triethyl phosphite and the appropriate carboxylic anhydridewas found to constitute an efficient method for the conversion of azetidinyl benzthiazolyl disulphides into acylthioazetidinones, allowing a short synthesis of penem FCE 88891 from its penam-1- oxide precursor.
