Cephem compound, its production and its use for producing cephem antibiotics |
abstract |
A 3-[(E)-1-propenyl]cephem derivative represented by formula (I) :n nwherein R represents hydrogen, an amino protecting group or a group of formula (II) :n nin which R 3 is an amino protecting group, R 4 is a hydroxy protecting group, and W is -CH= or -N=, R 2 represent a carboxy protecting group and X represents hydrogen or chlorine ; or a salt thereof ; may be prepared by isomerizing the corresponding 3-[(Z)-1-propenyl]cephem compound in an inert organic solvent in the presence of an aromatic thiol. These compounds are useful as intermediates for cephem antibiotics. A compound of formula (I) wherein X is chlorine can be converted into a 3-[(E)-3- ammonio-1-propenyl]cephem derivative by reaction with a tertiary amine. |
