Synthesis and study of new nitrogen-containing heterocycles based on glycoluril derivatives

Abstract

Functionalization of some cyclic bisureas (glycolurils) and their methylol derivatives was investigated with the goal to obtain new azaheterocycles. The modification of tetra-N-methylglycoluril gave unknown before tetra-N-methylbisimidazolium tetrachloride and provided a possibility of the synthesis therefrom of glycoluril tetrafluoro derivatives.
