Enchainements heteroatomiques et leurs produits de cyclisation. VI. Nouvelle synthese de cephemes: acetyl-3 methyl-7 phtalimido-7 oxo-8 thia-5 aza-1 bycyclooctenes-2 diastereomers

The total synthesis of two diastereomeric cephems is described with three original steps in excellent yields: construction of the 1,3-thiazine ring via a (4+2) cycloaddition reaction, regioselective hydrogenation of the carbon-nitrogen double bond, and la

LACTAMISATION PAR LE BOP: ACETYL-3 METHYL-7 PHTALIMIDO-7 CEPHEME

A 1,3-thiazine with a prelactamic chain is obtained via a (4+2) cycloaddition reaction.The regioselective hydrogenation at 2,3 and subsequent lactamisation using BOP is described.
