Cyclic bis-benzimidazole ligands and metal complexes thereof

Cyclic bis benzimidazole ligands of the following formula are formed by contacting a (2-aminophenyl)-benzimidazole-4-carboxaldehyde ethylene acetal or a (2-nitrophenyl)-benzimidazole-4-benzaldehyde with an acid optionally in the presence of a metal or a metal salt. wherein R1and R2may be the same or different and are selected from H, an alkyl having 1 to 10 carbon atoms, a benzyl group, a substituted 2-ethylphenyl group, a carbonyl group, a phenyl substituent, a tosyl group, and an alkylsulfonate group; R3and R4may be the same or different and are selected from H, methyl, and ethyl; and R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, and R18may be the same or different and are selected from H, alkyl having 1 to 10 carbon atoms, fluoride, chloride, bromide, iodide, nitro, amino, a carboxylate, an ester, and a phenyl group.

An original way for synthesis of new nitro-benzothiadiazole derivatives

The C-alkylation reaction of 4-chloromethyl-7-nitro-2,1,3-benzothiadiazole with 2-nitropropane anion which is shown to proceed by an SRN1 mechanism is an original way for the synthesis of new 2,1,3-benzothiadiazoles.

Synthesis of a new type of "bent" heterocyclic benzimidazolo-pyridazinones

The synthesis of some new heterocyclic benzimidazolo-pyridazinines starting from 2,1,3-benzothiadiazole-4-carboxaldehyde 2 is described.Biological evaluation of all new compounds proved them to be inhibitors of phosphodiesterase III with no marked positiv
