4-Hydroxy-/4-oxo tautomerism in the series of 3-substituted 2-methyl-quinolin-4(1H)-ones has been studied by 13C NMR-spectroscopy and quantum-chemical methods in various approximations (restricted Hartree-Fock method, DFT and MP2) for the isolated molecul... see more

Halofuginone is a potential anti-malarial drug, which could exist as three possible tautomers. Herein, using density functional theory (DFT), and handling the solvent effects with the PCM model, the tautomerism of halo­fuginone was investigated. Intramole... see more

For the first time data concerning the reactions of N-alkylhydrazones of aliphatic ketones have been systematized. The possible reaction centres of hydrazones and the main lines of attack for electrophilic and nucleophilic reagents have been distinguished... see more

The literature sources concerning the importance of diacetyl (dialkoxycarbonyl) substituted hydroxycyclohexanones as highly functionalized carbocyclic compounds, on the one hand, as well as, on the other hand, the research prospects in the field of synthe... see more

The tautomerism of 4-hydrazinoquinazoline and its derivatives was investigated. Geometry and thermodynamic parameters were computed theoretically using Gaussian 03 software. All calculations were performed at the MP2 level of theory using the standard 6-3... see more



The paper is devoted to the synthesis of new 2-(methylamino)quinoline-3-carboxamide derivatives by the pyrimidine cycle hydrolytic cleavage of pyrimido[4,5-b]quinoline-2,4(1H,3H)-diones. These later were synthetized in high yields by interaction of availa... see more
