| Abstract: | New pathways of reaction between 1-methylthiourea or 1-methylurea and benzil bring about new derivatives of (2S*,3aR*,6aS*)-perhydro-3aH-1,3]dioxolo4,5-d]imidazole and racemic (4S*,5R*)-4-alkoxy-5-hydroxy-1-methyl-4,5-diphenylimidazolidine-2-thiones. Some of the obtained urea-and thiourea derivatives were characterized by X-ray diffraction, which showed their supramolecular organization governed by the directionality of hydrogen bonds at the acceptor side C=O or C=S groups. |
