摘要:
A process for photochemically converting 3-exomethylene cephams (or 1-carba(1-dethia)cephams or 1-oxa(1-dethia)cephams) from the corresponding 3-alkyl-3-cephem (or 1-carba(1-dethia)cephem or 1-oxa(1-dethia)cephem) is provided. Further provided are 3-cephams useful as intermediates to 3-cephem compounds.
