Аннотация

Reactions  of arylidenemalononitriles with  2-nitromethylene-substituted imidazolidine, hexahydropyrimidine   and  hexahydro-1,3-diazepine afforded the  title derivatives. Reaction of 2-nitromethylenehexahydropyrimidine  with benzylamine or  n-butylamine and formalin in a molar  ratio of 1:1:2 gave the hexahydro-1H-imidazo[1,2-c]pyrimidine derivatives. Treatment of 2-nitro- methyleneimidazolidine and hexahydropyrimidine with secondary aliphatic amines  and formalin in a molar ratio of 1:1:1 afforded corresponding methylene bis-compounds.
