Abstract

Primary amines cleave s-triazine completely under evolution of ammonia and formation of the corresponding N, N'-disubstituted formamidines. Applied to suitable diamines, this reaction which occurs under mild conditions and with high yields provides a valuable method for the synthesis of various heterocycles, such as imidazolines, tetrahydropyrimidines, purines, benzooxazoles and benzothiazoles.
