[Figure not available: see fulltext.] Condensation of aminoazoles with (2E)-(3-morpholin-4-yl)acrylonitrile and 3,3-diethoxypropionitrile was used to synthesize a series of azolo[1,5-a]pyrimidin-7-amines. It was established that the reactions with certain aminotriazoles gave mixtures of regioisomers: azolo[1,5-а]pyrimidin-7-amines and azolo[4,3-а]pyrimidin-5-amines.

A diversity of new 7-substituted[1,2,4]triazolo[1,5-a]pyrimidine and 6-substituted[1,2,4]triazolo[1,5-a]pyrimidine-7-amine derivatives has been synthesized via reaction of 3-amino-[1,2,4]triazole with enaminonitriles and enaminones. The regio orientation and the structure of the products were confirmed by spectral and analytical data and synthesis via an alternative route. The procedure proved to be simple, efficient, and high yielding, and diversities of [1,2,4]triazolo[1,5-a]pyrimidines were obtained.

A variety of aminoazoles were reacted with bidentate electrophiles producing azolopyrimidines. The regioselectivity of the nucleophilic attack could be defined from the 13C chemical shift of the pyrimidine carbons and through NOE experiments.
