  • New Convergent Synthesis of 1α,25-Dihydroxyvitamin D<sub>3</sub> and Its Analogues by Suzuki−Miyaura Coupling between A-Ring and C,D-Ring Parts
    作者:Takeshi Hanazawa、Akiko Koyama、Kunio Nakata、Sentaro Okamoto、Fumie Sato
    DOI:10.1021/jo0353435
    日期:2003.12.1
    A new convergent method for the synthesis of 1alpha,25-dihydroxyvitamin D-3 and its analogues has been developed that involves efficient preparation of the A-ring part la, (Z)-(3S,5R)-1-bromomethylene-3,5-bis(tert-butyldimethylsilyloxy)-2-methylenecyclohexane, starting from epichlorohydrin (4) and its Suzuki-Miyaura coupling reaction with the C,D-ring part 12. Thus, (R)-4 was converted to (3S,5R)-5-(tert-butyldimethylsilyloxy)-8-(trimethylsilyl)-oct-1-en-7-yn-3-ol (3a) through a ten-step reaction sequence in 49% overall yield. Compound 3a thus obtained was treated with a Ti(O-i-Pr)(4)/2 i-PrMgCl reagent and then with NBS to afford (Z)-(1S,2S,5R)-2-bromomethyl-3-[bromo(trimethylsilyl)methylene]-5-(tert-butyldimethylsilyloxy)cyclohexanol (10a) in 51% yield, from which la was obtained in 87% yield by sequential treatment with TBSCl/imidazole, DBU, and Cs2CO3. The resulting A-ring intermediate la was reacted with alkenylboronate 12 in the presence of a PdCl2(dppf) catalyst to furnish 1alpha,25-dihydroxyvitamin D-3 in 82% yield after protodesilylation. Similarly, all of the other three possible stereoisomers of A-ring parts 1b, 1c, and 1d were prepared, from which 1-epi-, 3-epi-, and 1,3-di-epi-1alpha,25-dihydroxyvitamin D-3 were synthesized by coupling with 12 in excellent yield, respectively. Starting from la and 1c, des-C,D-I(x,25-dihydroxyvitamin D-3 analogues, retiferol 13 and its 3-epi derivative, were also prepared, respectively.

  • Efficient Convergent Synthesis of 1α,25-Dihydroxyvitamin D<sub>3</sub> and Its Analogues by Suzuki−Miyaura Coupling
    作者:Takeshi Hanazawa、Akiko Koyama、Takeshi Wada、Eiko Morishige、Sentaro Okamoto、Fumie Sato

    日期:2003.2.1
    [reaction: see text] 1alpha,25-Dihydroxyvitamin D(3) was synthesized by the Suzuki-Miyaura coupling of the A-ring intermediate 1, which was efficiently prepared from readily available 1,7-enyne 2, with the corresponding boronate compound of the C,D-ring portion. The method was applied to prepare des-C,D analogues of 1alpha,25-dihydroxyvitamin D(3).
    [反应:请参见文本]通过A环中间体1的Suzuki-Miyaura偶联合成了1alpha,25-二羟基维生素D(3),该中间体是从容易获得的1,7-烯2与相应的硼酸酯化合物有效制备的C,D环部分。该方法适用于制备1α,25-二羟基维生素D(3)的des-C,D类似物。
