  • Total steroid synthesis employing substituted isoxazole derivatives
    申请人:Hoffmann-La Roche Inc.
    公开号:US03985771A1
    公开(公告)日:1976-10-12
    The novel intermediates and processes of this invention provide a new synthetic route for the preparation of pharmaceutically valuable 19-nor-steroids. Further, the intermediates and processes of the invention provide a novel route for the preparation of pharmaceutically valuable estrones. The present invention provides a facile total synthesis of 13.beta.-alkyl-C/D-trans-steroidal materials. This desirable result is obtained via a unique asymmetric induction followed by subsequent stereo-specific reaction steps. As a precursor to the steroidal Ring A, a 3,5-disubstituted-4-isoxazolylmethylene group is employed in this synthesis.
    本发明的新型中间体和工艺提供了一种新的合成途径,用于制备具有药用价值的19-去甲基类固醇。此外,本发明的中间体和工艺提供了一种新的途径,用于制备具有药用价值的雌酮。本发明提供了一种易于实现的13.beta.-烷基-C/D-反式类固醇材料的全合成。这种理想的结果是通过独特的不对称诱导,随后是立体特异性反应步骤获得的。作为类固醇环A的前体,本合成中采用了3,5-二取代-4-异噁唑基甲基基团。
  • Preparation of vinyl lactones and corresponding Mannich bases
    申请人:Hoffmann-La Roche Inc.
    公开号:US03984427A1
    公开(公告)日:1976-10-05
    Vinyl ketones and Mannich-bases obtained therefrom are useful as intermediates in the total synthesis of steroids having valuable pharmacological properties. These compounds are prepared by the low temperature reaction of a vinyl Grignard e.g., vinyl magnesium chloride with substituted .gamma., .delta. or .epsilon. lactones followed, if desired, by reaction of the vinyl ketone obtained with a primary or secondary amine. Particular compounds prepared by this procedure include 2-(2-substituted aminoethyl)-6-substituted-2-hydroxy-tetrahydropyrans and the tautomers thereof.
    乙烯基酮和由此获得的曼尼希碱在合成具有有价值的药理特性的类固醇的总合成中作为中间体非常有用。这些化合物通过乙烯基Grignard(例如乙烯基氯化镁)与取代的γ、δ或ε内酯的低温反应制备,然后,如果需要,通过乙烯基酮与一级或二级胺的反应制备。通过这种方法制备的特定化合物包括2-(2-取代基乙基)-6-取代基-2-羟基四氢吡喃和其互变异构体。
  • Isoxazolyl-substituted perhydrobenzindenes
