Chemical asymmetric syntheses of the key intermediates (4,6,8) for the \_\_ synthesis of monobactam antibiotics ( SQ 26776 (azthreonam), sulfazecin, and SQ 26180 ) are accomplished from I\*)-4-phenylsulfonyl-2-azetidinone. Recently much attention have been focused on the nonclassical B-lactam antibi
