Description

A kind of preparation method of Delmadinone
Technical field
The invention belongs to the preparation processes of steroid hormone drug, and in particular to arrive a kind of progestational hormone medicine Delmadinone acetic acid The preparation method of ester and its intermediate Delmadinone.
Background technique
Delmadinone acetate, chemical name are as follows: the pregnant steroid-Isosorbide-5-Nitrae of the chloro- 17a- acetoxyl group-of 6-, 6-, triolefin -3,20- diketone, It is a kind of efficient progestational hormone medicine, there is stronger decorporation cream effect, be clinically mainly used for the unsmooth fertility women of milk ejection and exist Promote milk ejection during lactation.It is in ox, sheep cultivation for promoting milk cow, milch goat milk ejection that it, which is applied at most, since effect is good, Side effect is low, and market application prospect is wide.The conventional production methods of delmadinone acetate are with 17a hydroxyl progesterone for original Material, through acetic anhydride diacetyl, bleaching powder chlorination, triethyl orthoformate etherificate, the four-step reactions such as DDQ (or tetrachloroquinone) dehydrogenation Serine progesterone acetate is first made, then on this basis with DDQ in 1 dehydrogenation, delmadinone acetate, synthetic route is made See attached drawing 1.The method is when preparing serine progesterone acetate, anti-with chlorination using diacetyl using 17a- hydroxyl progesterone as raw material It should treat different things alike, it is easy to operate, but impurity is more, purity difference.Etherificate and dehydrogenation reaction, it is molten that Shanghai Hua Lian pharmaceutical purpose benzene does etherification reaction Agent makees dehydrogenation reaction reagent with DDQ, toxic, and environmental protection is difficult to handle.Using low-temperature dehydrogenation technique, in addition intermediate purity difference, Cause that product purity is low, there are many impurity, and column chromatography is needed could to purify, and synthesize weight total recovery and there was only 27%, cost is very high.Lake Northern institute of Pharmaceutical Industry makees solvent using technique etherificate and the dehydrogenation for the treatment of different things alike with chloroform, monoethyl quinone does dehydrogenating agent, avoids Toxic benzene and DDQ are used, synthesis weight total recovery has been increased to 48%, but to use a large amount of chloroforms, and reaction impurities are more, Want column chromatography that could purify.When finally preparing delmadinone acetate, using DDQ by serine progesterone acetate 1 in dioxane Position dehydrogenation is made delmadinone acetate, and environmental protection is also difficult to handle, and it is more to have suffered in technique that there are side reactions, and impurity is more, product Purity is low, and environmental protection treatment is difficult, the problems such as production cost height.
