| titleOfInvention | Process for the conversion of the e-isomer of 6-(substituted methylene)-2-penems into the z-isomer |
| abstract | During the preparation of 6-(substituted methylene)-2-penem compounds (which are known for their antibacterial and beta -lactamase inhibitory properties) mixtures of the E-isomer and the Z-isomer may be formed. The Z-isomer is, however generally preferred, and the present invention provides a process whereby the E-isomer may be converted into the Z-isomer by reaction with an aromatic heterocyclic thiol in the presence of a base. |
