Novel amidino substituted heterocyclic compounds of furan serie; synthesis and photochemical synthesis

The compounds in title are synthesized because of their potential antitumor activity. They could serve as intercalators in the reaction with DNA of maligmant cells [1]. In the reaction of condensation of methyl-E-3-(5-formyl-2-furyl)-2-phenylacrylate with corresponding 4-amidino substituted o-phenylenediamines [2], [3] , were prepared new subsituted benzimidazoles.The prepared benzimidazoles gave in the reaction of photodehydrocyclization [4] the next compounds: methyl-2-[(5-N-isopropylamidino)benzimidazolyl]naphtho[2,1-b]furan-5-carboxylatehydrochloride 1, methyl-2-{[5-N-(2-imidazolinyl)]benzimidazolyl}naphtho[2,1-b]furan-5-carboxylatehydrochloride 2 and methyl-2-[(5-N-morpholinylamidino)benzimidazolyl]naphtho[2,1-b]furan-5-carboxylatehydrochloride 3. All compounds were characterized by 1H and 13C NMR, IR and UV and by elementary analysis.
