  摘要：

  An efficient route for the synthesis of benzimidazo[2,1-a]isoquinolines and its condensed analogues has been developed via the palladium-catalyzed cyclization/C-H activation of N-allyl and N-methallyl derivatives of benzimidazoles. (C) 2010 Elsevier Ltd. All rights reserved.

  Synthesis of aryl ring-fused benzimidazolequinones using 6-exo-trig radical cyclizations

  摘要：

  The preparation of alicyclic ring-fused tetracyclic and pentacyclic benzimidazoles containing one and two fused aryl rings, respectively, is achieved conveniently in three steps, including Bu3SnH-mediated 6-exo-trig cyclization of sigma-aryl radicals generated from 1-allyl-2-(omega-bromoaryl)benzimidazoles. Inclusion Of 4,7-dimethoxy substituents on the radical precursors allows access to aryl ring-fused benzimidazolequitiones, a Unique family of potential bioreductive anti-cancer agents.

• Synthesis and toxicity towards normal and cancer cell lines of benzimidazolequinones containing fused aromatic rings and 2-aromatic ring substituents

  A facile 6-exo-trig cyclization of sigma-aromatic radicals has allowed the synthesis of various aromatic ring fused benzimidazoles and benzimidazolequinones. The most highly conjugated naphthyl fused benzimidazolequinone, (5-methyl-5,6-dihydrobenzimidazo[2,1-a]benzo[f]isoquinoline-8,11-dione) showed the highest specificity towards human cervical (HeLa) and prostate (DU145) cancer cell lines with little toxicity towards a human normal (GM00637) cell line at doses of <1 mu M. In contrast, 2-aromatic ring substituted (benzimidazole-4,7-diones) analogues, benzimidazolequinone with a pyridine ring and mitomycin C were more toxic than the highly conjugated naphthyl fused benzimidazolequinone towards the normal cell line.
