| titleOfInvention | Cephalosporin derivatives and their preparation |
| abstract | 3-Vinylcephalosporin derivatives of the formula: <IMAGE> (I) in which the symbols R1 are phenyl radicals or radicals -OZ1 (it being possible for Z1 to be alkyl, 2,2,2-trichloroethyl or optionally substituted phenyl or benzyl, or for the radicals Z1 to form an alkylene radical), R2 is a radical which can be removed by an enzymatic method, or a protecting radical, and R3 and R4 are optionally substituted alkyl, or phenyl, or together form a saturated 5-membered or 6-membered heterocyclic ring optionally containing another hetero-atom, are new, crystallizable intermediates useful for the preparation of anti-bacterial cephalosporins. |
