The method of synthesizing condensed imidazo-heterocyclic systems has been extended to the production of N-benzylideneaminoimidazo[1,2-a]imidazoles (VI, VII), the successive hydrolysis and treatment with nitrous acid of which has enabled N-substituted imidazo[1,2-a]imidazoles to be obtained. A by-product of the synthesis is 1,2-dibenzylideneamino-4-phenyl-5-n-propylimidazole (VIII), the condensation of the reduction product of which with isatin leads to a tetracyclic system.
