    • A process for the production of a .DELTA..sup.4 -gonenic steroid having the formula ##SPC1##Wherein R represents a member selected from the group consisting of hydrogen and the acyl of an organic carboxylic acid having from 1 to 18 carbon atoms, R' represents an alkyl having from 1 to 4 carbon atoms, R.sup.iv represents a member selected from the group consisting of lower alkyl, lower alkenyl or lower alkynyl, and B represents a member selected from the group consisting of two hydrogens in the 9.alpha. and 10.beta. position and a double bond which comprises the steps of reacting a 3-ketal-4,5-seco-gonane-5-one with a ketalizing agent, oxidizing the resultant 3,5-diketal-4,5-seco-gonane-17.beta.-ol, reacting the resultant 3,5-diketal-4,5-seco-gonane-17-one with an organometallic compound, hydrolyzing the resultant 3,5-diketal-17.alpha.-R.sup.iv -4,5-seco-gonane-17.beta.-ol, cyclizing the resultant 17.alpha.-R.sup.iv -4,5-seco-gonane-17.beta.-ol-3,5-dione and recovering said .DELTA..sup.4 -gonenic steroid. The novel intermediates are also part of the invention. The .DELTA..sup.4 -gonenic steroids are known compounds having steroidal properties.
    • 一种制备具有式WHEREIN R的一种DELTA 4-型类固醇的方法,其选自氢和具有1至18个碳原子的有机羧酸的酰基,R'表示具有 1至4个碳原子,Riv表示选自低级烷基,低级烯基或低级炔基的成员,B表示选自9α和10β位中的两个氢和双键的成员 其包括使3-缩酮-4,5-二羟基喹啉-5-酮与缩酮剂反应的步骤,将所得3,5-二缩酮-4,5-二羟基-17β-醇氧化,使 所得的3,5-二缩酮-4,5-二缩酮-17-酮与有机金属化合物,水解所得的3,5-二缩酮-17α-1R-4,5-间苯二酚-17β-醇 ,使得到的17α-Riv-4,5-Seco-gonane-17β-羟基-3,5-二酮环化并回收所述DELTA4-型葡萄糖甾族化合物。 新颖的中间体也是本发明的一部分。 DELTA 4-Gonenic类固醇是具有甾体特性的已知化合物。
