2-Dimethylamino-4,6,7,8-tetrahydroimidazo[1,2-a]-sym-triazin-4-one synthesized by us previously is converted by the action of aryl isocyanates and arenesulfonyl chlorides into the corresponding derivatives of urea and N-arenesulfonyl-substituted imidazo-sym-triazinones. It was shown that 6-(2-chloroethoxy)-2-dimethylamino-4-(methoxycarbonylmethylamino)-sym-triazine is converted by thermolysis into 2-dimethylamino-8-methoxycarbonylmethyl-4,6,7,8-tetrahydroimidazo[1,2-a]-1,3,5-triazin-4-one, which is also obtained by the action of methyl bromoacetate on the imidazo-sym-triazinone.
Synthesis and thermal decomposition of halogenoalkoxy-, halogenoalkylthio-, and halogenoalkoxyamino-sym-triazines 13. Synthesis and thermolysis of 4,6-disubstituted 2-(2-chloroethoxy)- and 2-(2-chloroethylamino)-sym-triazines
A thiouronium‐basedsolid‐phasesynthesis of a 1,3,5‐triazine scaffold has been developed. The key feature of the synthesis is the use of a readily accessible solid‐supported thiouronium salt as a primary precursor for the stepwise assembly of the 1,3,5‐triazine substrate. The sulfur linker employed in the synthesis is stable under both acidic and basic conditions and is versatile enough to provide
