A new method for the synthesis of substituted pyrido[2,3-b] indoles (α-carbolines) (14, 27-31), featuring Pd-catalyzed cross coupling between pyridine and aniline derivatives and subsequent intramolecular cylization, has been developed. This method provided a highly convergent access to the tetracyclic segment (3) of the marine antitumor agents: grossularines-1 and -2 (1,2).
为取代的吡啶并[2,3的合成的新方法b〕吲哚(α咔啉)(14,27-31),具有吡啶和苯胺衍生物和随后分子内cylization之间Pd-催化的交叉偶联,已经研制成功。该方法提供了高度收敛的海洋抗肿瘤药物四环片段(3)的途径:grosularines-1和-2(1,2)。
