| titleOfInvention | A kind of preparation method of cynnematin and another purposes |
| abstract | The present invention relates to a kind of preparation method and another purposes of cynnematin, it is applicable to cephalosporin chemicals manufacturing enterprise.It discloses under the existence of solvent and alkali; 7-ADCA and side chain thioester carry out condensation reaction at a certain temperature; react complete and carry out extracting and demixing impurity elimination, activated carbon decolorizing; namely intermediate is generated; described intermediate is through using basic hydrolysis Deprotection; activated carbon decolorizing; re-use acid out crystalline substance and namely obtain (6R; 7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-(carboxylic methoxyimino) kharophen]-8-oxo-3-methyl-5-thia-1-azabicyclo [4.2.0] oct-2-ene-2-crude carboxylic acid, obtains fine work after refining.The invention solves subject matter method for making and another purposes, and this subject matter is better than or equals Cephradine, avoid the interference of current resistance. |
