  A Versatile Construction of the 8H-Quino[4,3-b]carbazole Ring System as a Potential DNA Binder

  摘要：

  A short synthesis of the quino[4,3-b]- and quino[3,4-b]carbazoles is reported. The key step of the synthesis involves the preparation of suitable 2,3-divinylindoles by consecutive Wittig reactions. The thermal electrocyclic reaction of the divinylindole with concomitant dehydrogenation in the presence of Pd-C gave the (nitroaryl)carbazole which on reductive cyclization led to the quinocarbazole. The cleavage of the phenylsulfonyl group followed by phosphorus oxychloride treatment and subsequent displacement of the chlorine with 3-(dimethylamino)-1-propylamine gave the title compound in 25% overall yield.

  A ZnBr2-mediated arylation of aryl/heteroaryl methyl bromides with arenes at 80 °C led to the formation of arylated products, which underwent subsequent 1,5-sigmatropic rearrangement followed by electrocyclization and aromatization with loss of a diethylmalonate unit to afford the corresponding annulated products.

  In this study, we present our findings on the synthesis of α-, β-, γ-carbolines via PIFA/BF3·OEt2-mediated intramolecular cyclization of isomeric azidomethyl(indolyl)acrylates. Alternately, 1,5,7-triazabicyclo[4.4.0]dec-5-ene/1,8-diazabicyclo(5.4.0)undec-7-ene (TBD/DBU)-mediated Michael addition followed by intramolecular cyclization of isomeric 2/3-(azidomethyl)indol-3/2-yl)acrylates also furnished

  在本研究中，我们展示了通过 PIFA/BF 3 ·OEt 2介导的异构叠氮甲基（吲哚基）丙烯酸酯的分子内环化合成 α-、β-、γ-咔啉的研究结果。或者，1,5,7-三氮杂双环[4.4.0]dec-5-ene/1,8-二氮杂双环(5.4.0)十一碳-7-烯 (TBD/DBU) 介导的迈克尔加成，然后进行异构体的分子内环化2/3-(叠氮甲基)吲哚-3/2-基)丙烯酸酯还提供了各自的β-和γ-咔啉衍生物。出乎意料的是，2-(叠氮基甲基)-3-(吲哚-3-基)丙烯酸酯的热解导致通过氮宾插入和重排形成5-(2-(苯基磺酰胺基)芳基)烟酸乙酯以及γ-咔啉和环化。异构2-(叠氮基甲基)-3-(吲哚-2-基)丙烯酸酯热解后产生预期的δ-咔啉。热分子内氮烯插入反应也可以扩展到获得吡啶并苯并噻吩、吡啶并噻吩和喹啉。

  日期：2005.6

  A variety of 1-phenylsulfonylindolylmethyl sulfides are selectively oxidized to the corresponding sulfoxides using a hitherto unexplored KF/m-CPBA system. A major advantage is the absence of over-oxidation. (c) 2005 Elsevier Ltd. All rights reserved.
