Syntheses of Some New N-Linked Pyimidine-2-amines with Pyrazinopyrimidines, Thienopyrimidines, and Benzazoles via Reactions of Various Nucleophiles with Cyanamides
New heterocycles containing 2-aminopyrimidine moiety linked with pyrazino[1,2-_c_]pyrimidines, thieno[2,3-_d_]pyrimidines, benzimidazoles, benzothiazoles, and benzoxazoles have been prepared by an efficient method starting from _N_-(pyrimidin-2-yl)cyanamides. Read more
