- Preparation method of medical intermediate
-
The invention relates to the field of medicine synthesis, and particularly to a preparation method of a medical intermediate. When the method is used for preparing cyanosafalacin B, safety in the production process is greatly improved, and operation is simple and convenient; and since the biotoxicity of alkyl-substituted cyanosilane is far lower than the biotoxicity of highly-toxic cyaniding reagents such as potassium cyanide, risks in the operation process are greatly reduced, and the method is beneficial to the protection of production personnel and the environment.
