titleOfInvention | Process for the preparation of β-lactam antibiotics |
abstract | The present invention provides a process for the preparation of a fused bicyclic β-lactam containing compound having an optionally salified free carboxylic acid group which process comprises the reaction of an ester of the formula (I): ##STR1## with halide ion; wherein R is the residue of the fused bicyclic β-lactam containing compound, R 1 is an alkyl group of 1-6 carbon atoms optionally substituted by an alkoxy group of 1-4 carbon atoms or is an optionally substituted phenyl group or an alkyl group of 1-4 carbon atoms substituted by an optionally substituted phenyl group; and R 2 is a hydrogen atom or an alkyl group of 1-4 carbon atoms or is joined to R 2 to form part of a 5- or 6- membered carbocyclic or heterocyclic ring. |
