  • Synthesis of indole alkaloid (−)-corynantheidol and formal synthesis of (−)-corynantheidine via one-pot asymmetric azaelectrocyclization
    作者:Yanwu Li、Toyoharu Kobayashi、Shigeo Katsumura
    DOI:10.1016/j.tetlet.2009.05.045
    日期:2009.8
    The highly efficient asymmetric total synthesis of indole alkaloid, ()-corynantheidol, containing a 2,4,5-trisubstituted piperidine core, was achieved using a new version of the one-pot azaelectrocyclization reaction. The formal synthesis of ()-corynantheidine was also achieved using the common synthetic intermediate for these corynantheines.
    使用一锅氮杂电环化反应的新版本,可以高效地完成包含2,4,5-三取代哌啶核的吲哚生物碱(-)- corynantheidol的不对称全合成。(-)- corynantheidine的正式合成也使用这些corynantheines的常用合成中间体完成。
