  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.
