Two procedures were developed for the synthesis of 17α-alkyl-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triols from 3-methoxy-estra-1,3,5(10),8(9),14(15)-pentaene-17-one (1) using photosensitized oxidation by atmospheric oxygen or ionic hydrogenation in the presence of oxygen. It was shown that 17α-hexynyl-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triol (23) and its 3-methoxy derivative (26) inhibit K+,Na+-ATPase
开发了两种方法用于从 3-甲氧基-estra-1,3,5(10) 合成 17α-烷基-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triols ),8(9),14(15)-pentaene-17-one (1) 使用大气氧的光敏氧化或在氧存在下的离子氢化。结果表明 17α-hexynyl-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triol (23) 及其 3-甲氧基衍生物 (26) 抑制 K+,Na+-ATPase ,随着含氧取代基引入 17 位,抑制程度增加。首次发现类固醇具有 α2-肾上腺素阻断作用。
