Process for producing 3-substituted cephem compound |
| abstract |
A process for producing a 3-substituted cephem compound from an allenyl- beta -lactam compound which can readily be prepared from an inexpensive penicillin compound in a short reaction path. The process comprises reacting an allenyl- beta -lactam compound with an organohalogen compound in the presence of an at least equimolar amount of a metal having a standard oxidation-reduction potential of -0.3 V/SCE or less and 0.0001 - 0.5 mol, per mole of the lactam, of a metallic compound having a standard oxidation-reduction potential higher than that of the above metal. |
