✦ Synopsis


The stereoselective synthesis of two precursors of tricyclic β-ring-forming reaction followed by the reduction of a functionalized aromatic substituent at C-4 of the β-lactam lactam antibiotics (trinems) has been attempted by a novel approach that involves a highly stereoselective azetidinone nucleus.

GV118819X, a novel tricyclic ␤-lactam antibiotic of GlaxoWellcome, is a racemic mixture of two diastereoisomers, A and B. Of the two diastereoisomers, only A is available as a pure compound. By analyzing mixtures of GV118819X and A, a partial phase diagram is constructed, which indicates the presenc
