Abstract
The present invention provides a kind of synthetic method of -17 beta-hydroxy -3- ketone of -17 Alpha-Methyl of furazabol intermediate androstane, and this method is with 4-AD (abbreviation 4AD) for raw material, is etherified by 3 ketone group alkene, 17 ketone group grignard additions;Then the catalytic hydrogenation reaction for first carrying out 5 ethylene linkages without sour water solution after grignard addition, finally carries out 3 alkene ethers again and -17 beta-hydroxy -3- ketone of -17 Alpha-Methyl of compound androstane, 99.0% or more HPLC purity is prepared in 17 double hydrolysis.The method of the present invention route is brief, and production technology is easy to control, environmental-friendly, and production cost is low, is suitble to industrial scale production.
Description
Technical field
The present invention relates to a kind of synthetic methods of medicine intermediate, male more particularly to a kind of furazabol intermediate
The synthetic method of -17 beta-hydroxy -3- ketone of -17 Alpha-Methyl of steroid.
Background technique
Furazabol (parallel (2, the 3-C) furazan of-17-5 α of beta-hydroxy of 17 Alpha-Methyl-androstane) also known as furazabol, Fu La
Miscellaneous vigorous (Furazabol), structural formula are as follows:
。
Furazabol is protein anabolic hormone class drug, can promote the synthesis of vivo protein and it is inhibited to decompose generation
It thanks, while there is effect for reducing blood fat, be suitable for hyperlipidemia and atherosclerosis.Furazabol intermediate androstane -17
The traditional synthesis technology of -17 beta-hydroxy -3- ketone of Alpha-Methyl be using Chinese yam saponin as raw material, by open loop, acylation, oxidation, hydrolysis,
The reactions such as elimination obtain diene, and diene obtains table hero through reactions such as oximate, Beckmann rearrangement, sour water solution, basic hydrolysis, catalytic hydrogenations
Then target product is prepared through grignard, addition, oxidation reaction in ketone.Conventional method step is long, multistep chromic anhydride in process route
Oxidation reaction can be generated containing a large amount of Cr6+And Cr3+Reluctant industrial wastewater, to manufacturing enterprise production bring it is very big
Environmental protection pressure.The factors such as reduction and national environmental protection policy, restraint of trade due to medicine source plant resource (yellow ginger) cultivated area influence soap
The price of element and diene constantly rises violently, and cost of material is high, status in short supply causes -17 β of -17 Alpha-Methyl of androstane -
The production cost of hydroxyl -3- ketone increases substantially with the market price, to including furazabol, adroyd, mesterolone, stanozolol
The world market of hormonal medicaments including alcohol etc. produces significant impact.
It is using cheap and easy to get with 4-AD (abbreviation 4AD) that saponin, diene are all steroidal compounds critical materials
Soybean oil by-product carry out microorganism conversion preparation.The raw material is since manufacturing enterprise is numerous, and supply is very sufficient, and price is only
Half of diene or so, and avoid pollution of chromium.The inexpensive 4AD easily purchased is got over as the application of steroid hormone drug critical materials
To be more taken seriously.
CN107417753A uses 4AD as alternative materials, through 17 ketone groups of acetone cyanohydrin or Cymag selective protection
Key intermediate cyanalcohol object, again through ethylene ketal, basic hydrolysis, catalytic hydrogenation, grignard addition, sour water solution and etc. made
Standby, synthesis route is as follows:
。
Above-mentioned process route is had biggish using being prepared by sterol through the 4-AD that microbial fermentation obtains
Cost advantage, process route is simple, raw material 4-AD is in liberal supply, but can produce in the synthesis of key intermediate cyanalcohol object
Give birth to a large amount of cyanide containing wastewaters, the cyanide ion concentration about 500-800ppm in the industrial wastewater.Due to having containing cyanogen compound
The industrial wastewater containing cyanide of hypertoxic characteristic, formation must be handled strictly, could be discharged after up to standard.According to national emission standard,
The Cyanide in Waste Water ion concentration of discharge must not exceed 5ppm, and processing difficulty is very big, and the immense pressure of environmental protection of enterprise processing restricts
Application of the process route in industrialized production.
CN107312051A is equally using 4AD as alternative materials, but changes process route and be etherified through 3- ketone groups
Protection, grignard addition, catalytic hydrogenation, sour water solution and etc. prepared, synthesis route is as follows:
。
3 ketone group alkene etherification protections, 17 ketone group grignard additions, 5 ethylene linkage catalysis are passed through with 4AD raw material in above-mentioned technique road
Add hydrogen, prepared by acidolysis four-step reaction, synthetic route is avoided without the cyano protection of 17 ketone groups containing cyanide ion play
The difficulty of malicious discharge of wastewater and processing.But the compound containing 3 ketone group alkene etherificate structures is all unstable, to moisture, acid-sensitive, holds
Facile hydrolysis is at ketenes.3- ethyoxyl-androstane -3,5- diene -17- ketone in the drying process, places just part quickly in air
It is converted into 4AD.It especially needs to be added hydrochloric acid in 17 ketone group grignard addition last handling processes of the process route and carries out 17
Acidolysis reaction obtains 17 hydroxyls, and very unstable in acid condition containing 3 ketone group alkene etherification protection compounds, in the acidity item
It is difficult to control under part and only carries out 17 acidolysis reactions, and the deprotection reaction without 3 ketone group alkene etherificate.Occur 17 at the same time
Position acidolysis and 3 ketone group alkene are etherified in de-protected situation, are continued lower step catalytic hydrogenation and are easy in target product hero
The isomerism impurity with 5 β H structures is introduced in -17 beta-hydroxy -3- ketone of -17 Alpha-Methyl of steroid, the impurity and product polarity are extremely
It is close, be difficult to remove, thus finally influence product purity.
