Реферат: The α-ureidoalkylation of N-(carboxyalkyl)ureas (ureido acids) with 1,3-H2 s-, 1,3-Me 2 s-, and 1,3-Et2 s-4,5-dihydroxyimidazolidin-2-ones was systematically studied. The yields of glycolurils were shown to decrease both in going from 1,3-H2 s- to 1,3-Me2 s- and 1,3-Et2 s- 4,5- dihydroxyimidazolidin-2-ones and with elongation and branching of the carboxyalkyl chain in the ureido acids under study. The optimal reaction time for most of ureido acids is 3 h. The reaction mechanism was proposed. This mechanism was partially confirmed by quantum chemical methods and 1H NMR spectroscopy. Crystals of a number of the newly synthesized compounds were studied by X-ray diffraction, and two new conglomerates were found. A method was developed for the enantiomeric analysis of some racemic N-(carboxyalkyl)-glycolurils by chiral-phase HPLC.
