The first total synthesis of (±)-noruleine and a concisesynthesis of (±)-uleine have been accomplished via the DDQ mediated dehydrogenative cyclization of a tetrahydrocarbazole derivative bearing a non-substituted amide functionality to prepare the key azocino[4,3-b]indole precursor.

An efficient new pathway for (±)-dasycarpidone has been synthesized. The most important step in the synthesis of (±)-dasycarpidone is the intramolecular cyclization of the azocino[4,3-b]indole skeleton, which is constructed via tetrafluoro-1,4-benzoquinone and tetrachloro-1,4-benzoquinone and a mediated dehydrogenative cyclization of a tetrahydrocarbazole derivative possessing an amide side chain and
已经合成了 (±)-dasycarpidone 的有效新途径。(±)-dasycarpidone 合成中最重要的步骤是 azocino[4,3-b]indole 骨架的分子内环化,它是通过四氟-1,4-苯醌和四氯-1,4-苯醌构建的,具有酰胺侧链并以高产率完成的四氢咔唑衍生物的介导脱氢环化。使用光谱方法(FT-IR、 1 H NMR、 13 C NMR)确认所有目前合成的化合物的结构。
Studies on the synthesis of 4-oxo-2,3,4,9-tetrahydrocarbazole derivatives
In this study, a new synthetic route for the synthesis of 1‐hydroxy‐4‐oxo‐1,2,3,4‐tetrahydrocarbazole derivatives 12 and 13 from lactone 11 is described. Unfortunately, cyclization of compounds 12 and 13 to their respective azocino[4,3‐b]indole derivatives 14 and 15 was unsuccessful. J. Heterocyclic Chem., (2009).
