A new route for the synthesis of the title ring systems starting with the cinnamoylacetonitrile arylhydrazones (Ia, Ib) is described. It involves the self-cyclization of I which was found to be pH dependent.

The reactions of aroylisocyanates with 2-cyanomethylbenzimidazole (1) lead to the formation of 1:1 adducts (2a,b,c) and the corresponding α-aroyl derivatives (4a,b,c). The adducts (2a,b) could be cyclized affording pyrimido [3,4-a] benzimidazole der

An approach to the title ring system starting with the available cinnamoyloximinoacetonitrile (1) is proposed. It involves its reaction with various nucleophiles and subsequent addition of the resulting pyrrole derivatives (3,4) to 2-substituted cinn
