2-dicyanovinyl)-N2-substituted-formainidines react with dimethylformamide diethyl acetal at room temperature to give 6-cyanopurines as the major product together with novel 5-amino-2-arylimino-3,4-di[(N,N-dimethylamino)methylideneamino]-2H-pyrroles, which have been fully characterised and a single crystal X-ray analysis has been carried out on the N-phenyl derivative.
(Z)-N 1-(2-氨基-1,2-二氰基ovinyl )-N 2-取代的-mainmainidines在室温下与二甲基甲酰胺二乙基乙缩醛反应,以6-氰基嘌呤为主要产物,并与新型的5-amino-2 -芳基-3-3,4-二[(N,N-二甲基氨基)亚甲基氨基] -2 H-吡咯已经被充分表征,并且已经对N-苯基衍生物进行了单晶X射线分析。
