Abstract: Efficient and regioselective on-water synthesis of variously substituted 5-amino-4,7-dihydropyrazolo[1,5-a]pyrimidine-6-carbonitriles and 5-amino-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitriles using 1,8-diazabicyclo[5.4.0]undec-7-ene as catalyst has been demonstrated. The reaction of 2-benzylidenemalononitriles and 3-aryl-1H-pyrazol-5-amines or 1H-1,2,4-triazol-5-amine allows to obtain the respective pyrazolo[1,5-a]pyrimidines and [1,2,4]triazolo[1,5-a]pyrimidines in… read more here.
