indole alkaloids with novel skeletons and multiple chiral centers are described. Synthesis of these alkaloids was achieved by a simple one‐step reaction using strictosidine and 12‐aza‐strictosidine as the key intermediates. Strictosidines were prepared by coupling of secologanin with tryptamine and 7‐aza‐tryptamine, respectively, using the immobilized recombinant Rauvolfia strictosidine synthase. A detailed
描述了具有新颖骨架和多个手性中心的细胞毒性单萜类吲哚生物碱的简便化学合成。这些生物碱的合成是通过简单的一步反应完成的,其中使用了严格的核糖体和12-氮杂-严格的核糖体作为关键中间体。使用固定化的重组Rauvolfiastrictosidine合酶,将secologanin分别与色胺和7-氮杂-色胺偶联来制备均三糖苷。本文提供了详细的立体化学分析。结果为化学酶方法提供了机会,该化学酶方法导致具有改进的结构和活性的复杂生物碱的多样化增加。
