A convenient method for the preparation of imidazobenzimidazole 3, imidazoimidazole 5, imidazotriazole 6 and pyrano [2, 3-c] oxazole 7 derivatives is described. This depends on interaction of 2-methyl-4-arylidene-2-oxazolin-5-ones 1 with o-diamines, thiosemicarbazide and/or ethylcyanoacetate. The effect of alcoholic potassium cyanide on axazolinone 1 was studied. Antibacterial activity of the obtained products was studied.
