摘要：
This invention relates to novel substituted ceph-3-ems some of which are of value as intermediates in the synthesis of antimicrobially active cephalosporin analogues whilst others are useful as antimicrobial agents in their own right. The invention is described in Part D of this specification. Parts A, B, C and E relate to starting materials and processes necessary for the preparation of the novel cephems.
