  3-hydroxyestra-1,3,5(10)-triene-17β-carboxylic acid tert-butylamide 在 palladium diacetate 焦硫酰氟 、 1,3-双(二苯基膦)丙烷 、 三乙胺 作用下， 以 二氯甲烷 、 二甲基亚砜 为溶剂， -8.0~75.0 ℃ 、48.26 kPa 条件下， 反应 3.0h， 生成 3-(methoxycarbonyl)estra-1,3,5(10)-triene-17β-carboxylic acid tert-butylamide

  名称：

  A Novel, Practical Synthesis of Estra-1,3,5(10)-triene-3,17.beta.-dicarboxylic Acid 17-tert-Butylamide (SK&F 105656) from Estrone, via a Palladium-Catalyzed Methoxycarbonylation of a 3-Fluorosulfonate

  摘要：

  The title compound was prepared in nine steps from estrone in 22% overall yield. Each step was performed on a 50-150 gal scale and 3.5 kg of the title compound was prepared. Estrone was converted to its 3-methanesulfonate with methanesulfonyl chloride. The 17-cyanohydrin was prepared using trimethylsilyl cyanide. Dehydration with phosphorus oxychloride/pyridine followed by Pd/C-catalyzed hydrogenation gave the 17 beta-cyano-3-hydroxyestra-1,3,5(10), 16-tetraen-3-yl methanesulfonate derivative stereoselectively. Hydrolysis with sodium hydroxide in ethylene glycol gave a 3/1 beta/alpha mixture of l7-carboxylic acid isomers. Reaction with Vilsmeier reagent and quenching into tert-butylamine, followed by selective crystallization, yielded the desired 3-hydroxyestra-1,3,5(10)-triene-17 beta-carboxylic acid tert-butylamide. Reaction with fluorosulfonic anhydride yielded the S-fluorosulfonate. Palladium-catalyzed carbonylation in the presence of methanol gave the S-carboxylic acid methyl ester, which was saponified to yield SK&F 105656.
