  描述：

  12-Benzenesulfonyl-2,3-dimethoxy-5,12-dihydro-5,12-diaza-indeno[1,2-b]phenanthren-6-one 在 sodium hydroxide 作用下， 以 二甲基亚砜 为溶剂， 反应 10.0h， 生成 4,5-Dimethoxy-8H-quino<4,3-b>carbazol-1(2H)-one

  名称：

  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.
