Process for producing exo-methylenepenam compounds |
| abstract |
A process for preparing an exo-methylenepenamncompound represented by the formula (2) wherein cephemncompound represented by the formula (1) is reduced with anmetal having a standard oxidation-reduction potential of up ton-0.3 (V/SCE) in an amount of at least one mole per mole of thencephem compound and with a metal compound having a highernstandard oxidation reduction potential than the metal in annamount of 0.0001 to 10 moles per mole of the cephem compoundnto obtain the exo-methylenepenam compoundn nwherein R 1 is a hydrogen atom, amino or protected amino, R 2 isna hydrogen atom, halogen atom, etc. R 3 is a hydrogen atom orncarboxylic acid protective group, X is a halogen atom, etc.n nwherein R 1 , R 2 and R 3 are as defined above. |
