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

Functionalization of some cyclic bisureas (glycolurils) and their methylol derivatives was investigated with the goal to obtain new azaheterocycles. The modification tetrachloride and provided a possibility of the synthesis therefro...

Glycoluril Dimer Isomerization under Aqueous Acidic Conditions

A water-soluble methylene-bridged glycoluril dimer 2S was isolated. It was shown that 2S is the only kinetic product of the reaction between glycoluril derivative 1 and paraformaldehyde. Compound 2S is subsequently intermol...

Crystal Engineering of Glycoluril Dimers

We have prepared methylene-bridged glycoluril dimers bearing two hydrogen atoms on the convex face of the glycoluril unit. A new method for the synthesis of 1,6-substituted glycolurils was developed. In the solid state, 3c ...

Propanediurea-Based Molecular Clips Bind Halide Anions: An Insight into the Mechanism of Cucurbituril Formation

The synthesis and supramolecular properties of the first methylene-bridged propanediurea-based dimers are described. These dimers, bearing an aromatic sidewall, have the shape of molecular clips. Unlike glycoluril-based dimers, these clips n...
