Reaction of Disubstituted Cyanamides with Formamides under High Pressure
摘要:
High pressure-assisted co-cyclization of disubstituted cyanamides with formamide or monosubstituted formamides gave 2-amino- or 2-monosubstituted amino-4,6-bis(disubstituted amino)-1,3,5-triazines in one pot.

In aceticacidmedium, 2-chloro-4,6-dimorpholin-4-yl-[1,3,5]triazine undergoes amination by bifunctionalheterocycliccompoundscontaining both amino and thioamidegroups. The reactions are high-yielding and selective; the thioamide functions are unaffected under the requisite conditions. The reactions do not proceed in satisfactory yields in other solvents and, thus, require aceticacid. The resulting
