| titleOfInvention | A kind of preparation method of 16-ene steroid compound |
| abstract | The invention provides a preparation method of a 16-ene steroid compound. The compound of formula I is used as a substrate, and trimethylhalosilane is used as a dehydrating agent. The methyl halosilane is selected from one or more of trimethylchlorosilane, trimethylbromosilane and trimethyliodosilane. The beneficial effect of the present invention is to provide a method for preparing a 16-ene steroid compound with mild reaction conditions, friendly environment, easy operation, low cost and high molar yield, using trimethylhalosilane as a dehydrating agent, which is cheap and easy to obtain, The new process of the invention has more industrial value, can effectively control side reactions, and improve the reaction yield and quality. |
