  A novel method for the synthesis of benzimidazole-based 1,4-quinone derivatives

  摘要：

  An efficient method for the synthesis of 8-hydroxypyrido[1,2-a]benzimidazole-6,9-dione derivatives is described. This approach provides convenient access to hydroxypyrido[1,2-a]benzimidazole-6,9-dione analogs bearing electron withdrawing or electron donating substituents under mild reaction conditions.

  Synthesis of 6,7-dichloropyrido[1,2-a]benzimidazole-8,9-dione and its analogues and their reactions with nucleophiles

  摘要：

  Novel 6,7-dichloropyrido[1,2-a]benzimidazole-8,9-dione derivatives and its analogues were synthesized directly from chloranil and different 2-amino(di)azines without using a catalyst or activation. Further nucleophilic substitution reactions were carried out. (C) 2013 Elsevier Ltd. All rights reserved.
