Syntheses of steroids such as 3-hydroxy-7&agr;-methyl-21-[2′-methoxy-4′-(diethylaminomethyl)-phenoxy]-19-norpregna-1,3,5(10)triene citrate (“SR 16234”) and analogs thereof are provided, wherein 21-hydroxy-19-norpregna-4-en-3-one serves as a starting material or intermediate. The latter compound may be readily prepared from estrone-3-methyl ether. Certain intermediates in these syntheses also have value as therapeutic agents, for example in the treatment of prostate disorders such as prostatic cancer.
本文提供了合成类固醇如3-羟基-7α-甲基-21-[2'-甲氧基-4'-(二乙胺甲基)-苯氧基]-19-去甲孕烷-1,3,5(10)三烯酸盐(“SR 16234”)及其类似物的方法,其中21-羟基-19-去甲孕-4-烯-3-酮作为起始材料或中间体。后者化合物可以从雌甾酮-3-甲基醚中轻松制备。这些合成中的某些中间体也具有治疗价值,例如在治疗前列腺疾病如前列腺癌方面。
