5.alpha., 17B-Diacetoxy-6 -chloro-2.alpha., 3.alpha.; 16.alpha., 17.alpha.-diepoxy-androstane; 5.alpha., 17B-Dicetoxy-6 -chloro-androsta-2,16-diene; 5.alpha.-Hydroxy-6 -chloro-17-oxo-androst-2-ene or a like intermediate in the production of curare-like compounds is produced by reacting 5.alpha., 6B-dihydroxy-17-oxo-androst-2-ene with an organic sulfonic acid chloride. The obtained 5.alpha.- hydroxy-6B-chloro-17-oxo-androst-2-ene can then be reacted with the enol acetate of a ketone having 3 to 5 carbon atoms to yield 5.alpha., 17B-diacetoxy-6B-chloro-androsta-2,16-diene. The latter is treated to yield the corresponding diepoxide.
5.alpha.-Hydroxy-6-chloro-17-oxo-androst-2-ene或类似中间体在生产类似鬼箭草化合物时通过将5.alpha.,6B-二羟基-17-酮基-雄烯-2-烯与有机
磺酸氯反应产生。然后,得到的5.alpha.-羟基-6B-
氯-17-酮基-雄烯-2-烯可以与具有3至5个碳原子的酮的烯醇
乙酸酯反应,以产生5.alpha.,17B-
二乙酰氧基-6B-
氯-雄甾-2,16-二烯。后者经处理可得到相应的双
环氧化物。
