  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 Synthetic Approach to Ervatamine-Silicine Alkaloids. Enantioselective Total Synthesis of (−)-16-Episilicine
  作者：Mercedes Amat、Núria Llor、Begoña Checa、Elies Molins、Joan Bosch

  DOI：10.1021/jo902346j

  日期：2010.1.1

  Starting from an appropriate unsaturated phenylglycinol-derived oxazolopiperidone lactam, the synthesis of (−)-16-episilicine is reported, the key steps being a stereoselective conjugate addition, a stereoselective alkylation, and a ring-closing metathesis reaction. This represents the first enantioselective total synthesis of an alkaloid of the silicine group.

  从合适的不饱和苯基甘醇衍生的恶唑并哌啶酮内酰胺开始，据报道合成了（-）-16-哌啶子碱，关键步骤是立体选择性共轭加成，立体选择性烷基化和闭环易位反应。这代表了硅基生物碱的第一个对映选择性全合成。

  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。
