Process for preparing exo-methylenepenam compounds |
| abstract |
The present invention provides a process for for preparing an exo-methylenepenam compound represented by the general formula (5) characterized in that a beta -lactam halide compound represented by the general formula (2) is reduced with a metal having a standard oxidation-reduction potential of up to -0.3 (V/SCE) in an amount of at least one mole per mole of the halide compound and with a metal compound having a higher standard oxidation-reduction potential than the metal in an amount of 0.0001 to 10 moles per mole of the halide compound, or is subjected to an electroreduction process to obtain the exo-methylenepenam compound. <CHEM> |
