Three components cyclocondensations of the imidazole derivative (1c) with aroyl isothiocyanates afforded 6,7,8,8a-tetrahydro-3-aroylimidazo[1,2-a][1,3,5]triazine-2,4(3H,8H)dithiones (5a-e), while similar reaction with ethoxycarbonyl isothiocyanate led to the formation of ethyl 5-thioxo-2,3,8,9-tetrahydro-5H-diimidazo[1,2-a:1’,2;-c]-[1,3,5]triazine-6-carboxylate (10).
