  摘要：

  Abstract7‐Phenylacetamido‐3‐trifluoroacetoxymethyl‐ceph‐2‐em‐4‐carboxlic acid (7), which is easily produced from the iso‐cephalosporanic acid derivatives 4 or 6 by treatment with trifluoroacetic acid, reacts smoothly with ‘C‐nucleophiles’ to give derivatives of type 5 (Schema 1 and 2). Compounds 5 are converted into microbiologically active cephalosporins of type 8 (Table) by previously described methods.
