New Synthesis of 2,4,6,8-Tetramethyl-2,4,6,8-tetraazabicyclo[3.3.0]octane-3,7-dione Using Etidronic Acid as a 'Green' Catalyst
Autor: V.S. Malkov, S. Yu. Panshina, A. A. Bakibaev, O.V. Ponomarenko
Publikováno v: Russian Journal of Organic Chemistry. 56:2067-2073
A new method has been developed for the synthesis of 2,4,6,8-tetramethyl-2,4,6,8-tetraazabicyclo[3.3.0]octane-3,7-dione in 62% yield using etidronic acid [1-hydroxyethane-1,1-diylbis(phosphonic acid), HEDP] as a “green” catalyst. A plausible step

Autor: V.S. Malkov, A. A. Bakibaev, O.V. Ponomarenko, S. Yu. Panshina
Publikováno v: Journal of Structural Chemistry. 61:1315-1355
The paper discusses the results of X-ray diffraction studies of 2,4,6,8-tetraazabicyclo[3.3.0.]octane-3,7-dione (glycoluril) and its derivatives. Geometrical characteristics of glycoluril derivative molecules are analyzed depending on the type of the

Urea salts with 1-hydroxyethylidene diphosphonic acid
Autor: S. I. Belykh, V.S. Malkov, K. B. Zhumanov, S. I. Gorbin, N. V. Ponarin, A. A. Bakibaev, O.A. Kotelnikov, S. Yu. Panshina
Publikováno v: Russian journal of general chemistry. 2021. Vol. 91, № 3. P. 379-382
The reaction of urea with 1-hydroxyethylidene diphosphonic acid in the ratios of 1 : 1, 1 : 2, 1 : 3 was first studied. As a result of the reactions, the corresponding 1 : 2 or 2 : 1 salts were formed, which can exhibit biological activity. The synth

Efficient synthesis of tetraacetylglycoluril in the presence of phosphorus-containing catalysts
Autor: V.S. Malkov, A. E. Ukhov, N. F. Hoang, A. A. Bakibaev, D. A. Kurgachev, S. Yu. Panshina, K. B. Zhumanov
Publikováno v: Russian journal of physical chemistry. 2021. Vol. 57, № 1. P. 58-63
The effect of phosphorus-containing catalysts, namely phosphorous acid, phosphoric acid, diethyl hydrogen phosphite, and 1-hydroxyethane-1,1-diyldiphosphonic acid (HEDP), in the synthesis of tetraacetylglycoluril by acylation of glycoluril with aceti
