17-hydroxy-6-methylenepregn-4-ene-3,20-dione 17-acetate - Production method
16, 17α-epoxypregnan-4-ene-3, 20-dione (I. e. epoxyprogesterone) can be used by (epoxy group and hydrogen bromide) addition, catalytic hydrogenation (except 16-position Bromine), (3-ketone, 17 α-hydroxy) acetylation (simultaneous formation of 3-position and 5-position double bonds), hydrolysis (removal of 3-position acetyl group, 3-ketone, 4-diene recovery), to generate 17 α-acetoxy progesterone (ie 17 α-hydroxypregnost-4-ene-3, 20-dike-17-acetate), then (3-position with triethyl orthoformate) etherification, (6-position with dimethylformamide) formylation and reduction to obtain 3-ethoxy-17α-hydroxy-6-hydroxymethylpregnant-3-, 5-diene-20-keto-17-acetate, and finally hydrolysis (3-position keto, 4-position double bond recovery, and form 6-position methylene) to obtain the product.
