| titleOfInvention | Preparation method of tylosin |
| abstract | The invention belongs to the technical field of medicines, and particularly relates to a preparation method of tylosin. The tylosin of the invention is prepared by reacting a compound N-9, N-butyllithium and a compound N-8 to obtain a compound N-10-a, then adding triethylsilane and boron trifluoride diethyl etherate to react to obtain a compound N-11, and then adding Lewis acid to react. The preparation method shortens the synthetic route of the tylosin, and the obtained tylosin has high yield, low impurity content and stable property. |
