    摘要: Cephalosporin antibiotics having a 3-position substituent of the formula:
    -CH₂NR¹-Y-A-Z-Q
    are described, wherein R¹ is hydrogen or certain optionally substituted alkyl groups; Y is -CO- or -SO₂-;
    A is optionally substituted phenylene or heterocyclylene;
    Z is a linking group and Q is a catechol or related ring system.
    Processes for their preparation and use are described.
