    摘要: The present invention provides a process for the substitution of an acylamino β-lactam compound at the carbon atom carrying the acylamino group, which process comprises reacting the β-lactam compound with an halogenating agent and a nucleophilic reagent; characterised in that the acylamino group has an acidic group on the carbon atom adjacent the carbonyl group.
    In particular the process of this invention comprises reacting a β-lactam of partial structure (I):
    where X represents an acidic group; with an halogenating agent and a nucleophilic reagent.
