    Four epimeric 15- and 16-hydroxy steroids have been stereoselectively synthesized from epi-androsterone. The key intermediate is the 3β-[(tert-butyldimethylsilyl)oxy]-5α-23,24-bisnorchol-16-en-22-ol (10), which allows both efficient D-ring functionalization and the possibility of facile side-chain construction. In the course of this synthesis, we have found that the stereochemical outcome of the C-15
    四种差向异构 15-和 16-羟基类固醇已从表雄酮立体选择性地合成。关键中间体是 3β-[(叔丁基二甲基甲硅烷基)oxy]-5α-23,24-bisnorchol-16-en-22-ol (10),它允许有效的 D 环功能化和容易的侧-链建设。在此合成过程中,我们发现 C-15 羰基还原的立体化学结果强烈依赖于 C-16 和 C-17 杂交。

    Abstract Two strategies have been explored for the synthesis of steroidal 20,16-γ-carbolactones from the corresponding 17-ketoandrostane. A highly efficient, stereospecific protocol has been developed for the β-oriented cis-γ-lactone, based on a Michael addition of cyanide to a conjugated ketone. A different approach, involving prior attachment of a 3-carbon side chain on C-17 of a 17-oxo-16β-acetoxy-androstane

  • Mechanistic studies of the rearrangements of steroidal 16,17-ketols and syntheses of 20→16-cis-γ-carbolactones
    作者:Andrea C Bruttomesso、Darı́o Doller、Eduardo G Gros

    日期:1999.5
    Utilization of 17-keto-androstanes as starting materials for the synthesis of alpha- or beta-oriented steroidal 20-->16-gamma-carbolactones has been explored following two different strategies. A highly efficient, stereospecific protocol has been developed for the beta-oriented cis-gamma-lactone. A different approach, involving prior attachment of a 3-carbon side chain on C-17 of a 17-oxo-16 beta-acetoxyandrostane led to the epimeric, cc-oriented lactone. The mechanism of the rearrangement of epimeric 16 beta- or 16 alpha-hydroxy-17-ketoandrostanes to 17 beta-hydroxy-16-keto-androstanes was studied by C-13 NMR spectroscopy. The former occurs through a 1,2-sigmatropic H-shift, while the latter is likely to take place by simple enolization-reprotonation. (C) 1999 Elsevier Science Ltd. All rights reserved.
