  Indolecarbonyl Coupling Reactions Promoted by Samarium Diiodide. Application to the Synthesis of Indole-Fused Compounds

  摘要：

  By the assistance of an N-sulfonyl group or a cyano group at the C-2 position, hydroxyalkylations of indole-3-carbonyls were achieved by the promotion of samarium diiodide. The indolecarbonyl coupling reactions proceeded in high stereoselectivity via chelate transition states. Intramolecular indolecarbonyl couplings of 1-(3-oxopropyl)indole-3-carboxaldehydes were realized as the indole-carbonyl group was more reactive toward SmI2 than the aliphatic carbonyl group. Elaboration of the coupling products with oxidizing agents, acid, phosphorus pentasulfide (or Lawesson's reagent), amines, and hydrazine led to a variety of indole derivatives and indole-fused polycyclic compounds of synthetic interest and pharmaceutical uses.

  3-Formyl-, 3-acetyl-1-methylindole and their 2-cyano analogues undergo intra- and inter-molecular hydroxyalkylations on treatment with samarium(II) iodide in the presence of a cosolvent hexamethylphosphoramide; the intramolecular coupling products have the structure prototype of mytomycins and the intermolecular coupling products are readily converted to furoindoles as synthetic equivalents of indole-2,3-quinodimethanes.

  在助溶剂六甲基磷酰胺存在下，3-甲酰基-、3-乙酰基-1-甲基吲哚及其 2-氰基类似物在碘化钐（II）的处理下发生分子内和分子间羟烷基化反应；分子内偶联产物具有霉菌素的结构原型，分子间偶联产物很容易转化为呋喃吲哚，作为吲哚-2,3-喹啉二甲醚的合成等价物。
