Description

The novel method of a kind of synthesis 17 Alpha-hydroxy Progesterone
Technical field
The present invention relates to the synthesis of medicine intermediate, specifically, it relates to the novel method of a kind of synthesis 17 Alpha-hydroxy Progesterone.
Background technology
17 Alpha-hydroxy Progesterone are a kind of versatile intermediates producing steroid body corticosteroids medicine. Taking it as raw material, it is possible to produce the multiple common corticosteroids medicines such as medroxyprogestrone Acetate, cyproterone megestrol, hydrocortisone, prednisone.
The most traditional production method: extract diosgenin from Chinese yam plant; Saponin, through open loop, oxidation, hydrolysis, obtains key intermediate acetic acid gestation diene alcohol ketone (being called for short two alkene); Taking two alkene as raw material, through epoxidation, Ao Shi oxidation, the obtained 17 Alpha-hydroxy Progesterone of upper bromine, debrominate four-step reaction. Owing to Chinese yam plant resources is exhausted gradually, pollute big when extracting saponin, so saponin cost of material height. In addition follow-up synthesis step is long, and receipts rate is low, pollutes big, and cost is higher.
As follows from the reaction expression of production of saponin 17 Alpha-hydroxy Progesterone:
In addition, over the past two years, domestic according to foreign literature report, utilize and extract Stigmasterol from the residue that soybean oil is produced, through modern biotechnology fermentation technique, obtain another key intermediate 4-AD of synthesizing steroid hormonal medicaments, be called for short 4AD. Operated by 4AD produce 17 Alpha-hydroxy Progesterone through cyano group addition, 3 ketal protections (or 3 ether protections), 17 alpha-hydroxy alkene ether protections, grignard addition, the two multisteps such as protecting group, decolorizing and refining of hydrolysis again. Although raw material 4AD is more cheap than saponin, step is shorter, and receipts rate is higher, less pollution, and cost is lower, but still too complicated, and quality, cost, three wastes aspect still remain to be further improved.
The reaction expression following (CN103467555A) of 3 ketal protection routes:
3 ketal protection receipts rates are not high, and content is not high, and has the isomer of 4 double bonds, and this isomer can not get desired product when carrying out grignard addition, therefore last overall yield is lower, and quality is difficult to reach high standard requirement.
The reaction expression following (CN103910775A) of 3 ether protection routes:
3 ether protection is reversible, reaction is incomplete, and color is relatively dark, and quality is poor, and receipts rate is not high, therefore overall yield is lower, and quality is difficult to reach high standard requirement.
So comprehensive above synthesis technique is considered, a kind of simple synthetic method of exploitation, environmental protection, receipts rate height, cost is low, and quality is good, and the route being applicable to suitability for industrialized production just seems especially important.
Summary of the invention
In order to solve problems of the prior art, it is an object of the invention to provide a kind of simple, high quality and high receipts rate synthesizes the novel method of 17 Alpha-hydroxy Progesterone.
