| titleOfInvention | Cefem compound, preparation method thereof and use thereof for preparing cefem antibiotic |
| abstract | 3-[(E) -1-propenyl] cepem compound of formula (I):n n n n n n n n [Wherein R represents a protecting group of hydrogen, an amino group or a group of the following general formula (II):n n n n n n n n {Wherein R 3 is a protecting group of an amino group, R 4 is a protecting group of a hydroxyl group, W is -CH = or -N =} R 22 is a protecting group of a carboxyl group; X 1 represents hydrogen or chlorine] This compound is useful as an intermediate for the preparation of cefem antibiotics and isomerizes the corresponding 3-[(Z) -1-propenyl] cepem compound in an inert organic solvent in the presence of an aromatic tee. It is prepared by making. Compounds of formula (I) wherein X is chlorine may be converted to 3- (E) -1-propenyl] cepem derivatives by reaction with tertiary amines. |
