New Amidino-benzimidazolyl Thiophenes ; Synthesis and Photochemical Synthesis

New amidino-benzimidazolyl-substituted bis-1, 2-(2-thienyl)ethenes (4, 5, 6) and benzo[1, 2-b:4, 3-b’]dithiophenes (8, 9 and 10) were prepared by the condensation of amidino-substituted o-phenylene diamines with corresponding dialdehydes (3 and 7). All prepared amidino-benzimidazolyl substituted compounds, are of particular interest, because they could serve as intercalators or groove binders on DNA in anticancer therapy.
