Cephalosporin compounds |
摘要 |
Novel cephalosporin compounds having a substituted or unsubstituted vinyl group at the 3-position are prepared by the reaction of a phosphoranylidene compound with a compound containing a carbonyl group. The novel cephalosporin compounds are active against a range of gram-negative and gram-positive microorganisms and are of value in human and veterinary medicine.
