  • Azasteroids as inhibitors of rat prostatic 5.alpha.-reductase
    作者:Gary H. Rasmusson、Glenn F. Reynolds、Torleif Utne、Ronald B. Jobson、Raymond L. Primka、Charles Berman、Jerry R. Brooks
    DOI:10.1021/jm00378a028
    日期:1984.12
    were prepared from 3-keto-delta 4-precursors by oxidative (O3 or NaIO4-KMnO4) A-ring cleavage followed, in turn, by ring closure with an amine and hydrogenation over platinum catalyst. Other A-ring azasteroids were made by Beckmann rearrangement of oximes of 2-oxo-A-nor, 3-oxo- and 4-oxo-5 alpha-androstanes. An A-nor-2-oxo-3-azasteroid was prepared by oxidative decarbonylation of a precursor 2,3-dioxo-4-azasteroid
    已经制备了一系列A环杂环类固醇,并在体外测试了其对大鼠前列腺类固醇5α-还原酶的抑制作用。发现一组17个β-取代的4-甲基-4-氮杂-5α-雄甾烷-3-酮具有惊人的高抑制活性。这些化合物由3-酮-δ4前体通过氧化(O3或NaIO4-KMnO4)A环裂解,然后用胺闭环并在铂催化剂上氢化而制得。其他的A环氮杂甾类化合物是通过贝克曼重排2-oxo-A-nor,3-oxo-和4-oxo-5α-雄甾烷酮的肟制得的。通过用间氯过苯甲酸将前体2,3-二氧代-4-氮杂甾族化合物氧化脱羰制备A-正-2-氧代-3-氮杂甾族化合物。4-氮杂类固醇的A环修饰包括δ1-不饱和键,2-和4-取代基以及3-羰基取代基。
  • The first example of lipase-catalyzed resolution of a stereogenic center in steroid side chains by transesterification in organic solvent

    DOI:10.1016/0957-4166(96)00178-4
    日期:1996.6
    The Pseudomonas cepacia lipase selectively catalyzes the acylation of the (20S)-isomer of the 22-alcohol group in the C-22 steroid compounds 1a and 4a when the transesterification is irreversibly carried out with vinyl acetate in an organic solvent.

    An electrocatalytic system comprised of Cr-NiO/GF and Cr-Ni3N/GF (GF: graphite felt) was applied to anodic electrooxidation of sterol and the cathodic hydrogen evolution reaction (HER), with a high space-time yield of 48.85 kg m−3 h−1 for steroid carbonyl and 1.82 L h−1 for H2 in a two-layer stacked flow cell. This strategy could facilitate large-scale simultaneous production of H2 and value-added
