  • Symmetry-Driven Synthesis of Indole Alkaloids: Asymmetric Total Syntheses of (+)-Yohimbine, (-)-Yohimbone, (-)-Yohimbane, and (+)-Alloyohimbane
    作者:Jeffrey Aube、Shomir Ghosh、Mehmet Tanol
    DOI:10.1021/ja00099a019
    日期:1994.10
    Total asymmetric syntheses of the target alkaloids are reported. The syntheses involve the preparation of enantiomerically pure (S,S)-1,3,3a,4,7,7a-hexahydro-2(H)-inden-2-one 7 and its meso isomer 5. Each ketone is then converted into a ring-expanded lactam using an oxaziridine synthesis/rearrangement protocol. The applications of Bischler-Napieralski ring constructions along with appropriate functional group transformations afford enantiomerically enriched alloyohimbane or yohimbane from the meso- or C-2-symmetric ketones, respectively. A cis-5,6-diacetoxy compound (18) derived from the (S,S)-ketone served as the starting material for the total syntheses of the more highly functionalized alkaloids. Accordingly, a site-specific insertion of the indole-containing side chain was accomplished via stereoselective formation of an oxaziridine followed by its stereospecific rearrangement. The selectivity of this sequence allowed for the differentiation of alcohols at C-17 and C-18 (yohimbine numbering) and the synthesis of Delta 18,19-yohimbone. This alpha,beta-unsaturated ketone was converted into either (-)-yohimbone or (+)-yohimbine using standard chemistry.
  • Enantioselective Syntheses of (-)-Alloyohimbane and (-)-Yohimbane by an Efficient Enzymatic Desymmetrization Process
    作者:Arun K. Ghosh、Anindya Sarkar
    DOI:10.1002/ejoc.201601171
    日期:2016.12
    Enantioselective syntheses of (-)-alloyohimbane and (-)-yohimbane was accomplished in a convergent manner. The key step involved a modified mild protocol for the enantioselective enzymatic desymmetrization of meso-diacetate. The protocol provided convenient access to an optically active monoacetate in multi-gram scale in high enantiomeric purity. This monoacetate was converted to (-)-alloyohimbane
    (-)-alloyohimbane 和 (-)-yohimbane 的对映选择性合成以收敛的方式完成。关键步骤涉及用于内消旋二乙酸酯的对映选择性酶促去对称化的改良温和方案。该协议提供了对高对映体纯度的多克级光学活性单乙酸酯的便捷访问。该单乙酸酯被转化为(-)-alloyohimbane。衍生醛的还原胺化导致异构化,产生反式产物,并允许合成 (-)-育亨宾。
