| titleOfInvention |
Cephem compound, its production and its use for producing cephem antibiotics |
| abstract |
A 3-[(E)-1-propenyl]cephem compound represented by formula (I): wherein R represents hydrogen, a protective group for an amino group, or the group shown by formula (II): in which R3 is a protective group for an amino group, R4 is a protective group for a hydroxyl group, and W is -CH= or -N=; R2 represents a protective group for a carboxyl group; and X represents hydrogen or chlorine. The compound is useful as an intermediate for producing cephem antibiotics and is prepared by isomerizing the corresponding 3-[(Z)-1-propenyl]cephem compound in an inert organic solvent in the presence of an aromatic thiol. The compound of formula (I) wherein X is chlorine can be converted into a 3-[(E)-3-ammonio-1-propenyl]cephem derivative through the reaction with a tertiary amine. |
