  • Process and intermediates for the synthesis of vitamin D.sub.3
    申请人:Hoffmann-La Roche Inc.
    公开号:US04310467A1
    公开(公告)日:1982-01-12
    The present disclosure is directed to a process and intermediates for the synthesis of Vitamin D.sub.3 metabolites such as 1,25-dihydroxycholecalciferol, 25-hydroxycholecalciferol and 24R,25-dihydroxycholecalciferol from 17-keto steroids via intermediates having the natural steroid configuration at the 20-position. These novel intermediates are prepared from 17-keto steroids by reaction with ethyltriphenylphosphonium halides followed by reaction with formaldehyde to form comounds having the natural steroid configuration at the 20-position and which are suitable substrates for the preparation of the aforementioned Vitamin D.sub.3 metabolites.
    本公开涉及一种从17-酮类固醇经过具有20-位点天然类固醇结构的中间体合成维生素D.sub.3代谢物,如1,25-二羟基胆钙化醇、25-羟基胆钙化醇和24R,25-二羟基胆钙化醇的过程和中间体。这些新颖的中间体通过与乙基三苯基磷卤化物反应,然后与甲醛反应,形成具有20-位点天然类固醇结构的化合物,适用于制备上述维生素D.sub.3代谢物。

    (17) and C (20)) introduction of steroid side chains which are suitably functionalized for further elaboration is presented. The ene reaction of (17 Z)-ethylidene steroids, which are readily obtained from 17-keto steroids via a Wittig reaction, with various enophiles such as formaldehyde and acrylate esters leads to useful intermediates which contain the natural steroid configuration at C (20). Catalytic
    提出了一种简单而有效的新方法,用于高度立体选择性地(在C(17)和C(20)处)引入类固醇侧链,并适当地对其进行功能化以进行进一步的修饰。很容易通过Wittig反应从17-酮类固醇获得的(17 Z)-亚乙基类固醇与各种亲和剂如甲醛和丙烯酸酯的烯反应会生成有用的中间体,该中间体在C处具有天然类固醇构型(20) 。在Δ的催化氢化16 -双键来自α-面发生在C(17),以立体特异性生成正确的配置。通过使用2-氯丙烯酸甲酯作为亲热剂,也有选择地在C(23)处引入了另一个手性中心。

    A stereoselective synthesis of 6-oxo-23,24-dinor-5α-cholan-2α,3α,22-triyl triacetate 9 was achieved in 44% overall yield in nine steps starting from 3β-hydroxyandrost-5-en-17-one 8. The important features of this synthesis are the modified Wittig reaction on the 17-oxo steroid 8 and the stereospecific generation of the chiral centre at C-20 by a resin-catalysed ene reaction on (Z)-3β, p-tolylsulfonyloxypregna-5
