| titleOfInvention | A method of Tilmicosin is prepared using tylosin D as raw material |
| abstract | The present invention relates to a kind of methods for preparing Tilmicosin as raw material using tylosin D, this method is using tylosin D as raw material, 20 primary hydroxy groups are obtained into intermediate 1 for aldehyde radical by selective oxidant, de- mycaminose is hydrolyzed again obtains intermediate 2, by formic acid and 3,5 lupetidine reduction aminations obtain product Tilmicosin.The present invention is using tylosin D as raw material, by specific selective oxidant make tylosin D be changed into synthesis Tilmicosin effective component, it avoids being changed into impurity, a new way is opened for the preparation of Tilmicosin, solves the problems, such as that the existing impurity residual for preparing Tilmicosin using tylosin as starting material is high relatively low with yield. |
