  azo[4,5-e][1,2,4]triazin-6-ones, 4,5-bis(3-thiosemicarbazido(guanidinoamino))imidazolidin-2-ones, and 1,3-dialkyl-4-(guanidinoimino)imidazolidin-2-ones by α-ureidoalkylation of thiosemicarbazide or aminoguanidine were found. A novel conglomerate in the series of imidazolidin-2-one derivatives was detected: 4,5-bis(guanidinoamino)-1,3-dimethylimid-azolidin-2-one dihydrochloride dihydrate.

  The interaction of sulfonamides with 4,5-dihydroxyimidazolidin-2-ones was studied for the first time. The earlier unknown 4,4'-sulfonyldiiminobis(1,3-dialkylimidazolidin-2-ones) and 4(S)-aryl(alkyl)-sulfonyliminoimidazolidin-2-ones were synthesized. A probable pathway of the reaction was proposed. 1,3-Diethyl-4,5-dihydroxyimidazolidin-2-one was isolated and described.
• Enthalpies and heat capacities of solution of racemic N-methyl-substituted glycolurils in water at T=(278.15 to 313.15)K

  The molar enthalpies of solution of racemic (with enantiomer ratio of 1:1) 2-monomethyl-, 2,6-dimethyl-, and 2,4,6-trimethylglycolurils (2-MMGU, 2,6-DMGU and 2,4,6-TMGU, respectively) in water were measured calorimetrically in the temperature range between (278.15 and 313.15)K and at p=99.6 kPa. Derived from experimental data, the standard (at infinite dilution) molar enthalpic characteristics of the dissolution process are positive by sign and increase with rising temperature as well as in a sequence of 2,4,6-TMGU < 2,6-DMGU < 2-MMGU. In the same way, the standard heat capacity of solution decreases distinctly, leading to the conclusion that the effect of hydrophobic hydration is more pronounced for the more N-methylated solute. It was suggested that, despite the presence of hydrophobic moieties (N-sited methyl groups) in the molecules considered, a hydrophilic constituent (via H-bonding) seems to be the predominant one in the total enthalpy effect of a solute hydration.

  Two methods for the synthesis of previously unavailable 1-substituted semithioglycolurils were developed. These methods consist of the cyclocondensation of 1-substituted ureas with 4,5-dihydroxy- or 4,5-dimethoxyimidazolidine-2-thione or glyoxal, followed by the reaction of the resulting 1-substituted 4,5-dihydroxyimidazolidine-2-ones with HSCN in a two-step one-pot procedure.

  Two general procedures were developed for the synthesis of chiral N-mono-, N, N′-di-, N, N′ N″-tri-, and N, N′, N″, N′″-tetraalkylglycolurils based on the reactions of 4,5-dihydroxy-imidazolidin-2-ones or glyoxal with one or two moles of alkylureas, respectively, by acid catalysis. The reactions of N-monoalkyl- and N, N′-dialkylureas with glyoxal proceed regioselectively. The mechanism of these reactions was suggested and partly confirmed by quantum-chemical calculations and experimental data. The enantiomeric separation of some chiral glycolurils by chiral-phase HPLC was carried out for the first time.
