Two independent and consecutive Michael addition of 1,3-dimethylbarbituric acid to (2,6-diarylidene)cyclohexanone: Flying-bird-shaped 2D-polymeric structure

Abstract Two independent and consecutive intermolecular Michael addition of 1,3-dimethylbarbituric acid to 2,6-diarylidenecyclohexanone as an α,β-unsaturated ketone leads to synthesis of a new type of meso form 5,5′-((2-oxocyclohexane-1,3-diyl)bis(arylmethylene))bis(1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione) in good yield. These compounds showed a 2D-polymeric structure via intermolecular H-bonds. Structure elucidation is carried out by 1H NMR, 13C NMR, FT-IR, and X-ray diffraction analyses. A plausible reaction mechanism is discussed. Graphical abstract

期刊介绍： Heterocyclic Communications (HC) is a bimonthly, peer-reviewed journal publishing preliminary communications, research articles, and reviews on significant developments in all phases of heterocyclic chemistry, including general synthesis, natural products, computational analysis, considerable biological activity and inorganic ring systems. Clear presentation of experimental and computational data is strongly emphasized. Heterocyclic chemistry is a rapidly growing field. By some estimates original research papers in heterocyclic chemistry have increased to more than 60% of the current organic chemistry literature published. This explosive growth is even greater when considering heterocyclic research published in materials science, physical, biophysical, analytical, bioorganic, pharmaceutical, medicinal and natural products journals. There is a need, therefore, for a journal dedicated explicitly to heterocyclic chemistry and the properties of heterocyclic compounds.
