α-Ureidoalkylation of N-(2-acetylaminoethyl)ureas with various 4,5-dihydroxyimidazoli- din-2-ones was systematically studied. Novel N-(2-acetylaminoethyl)glycolurils were obtained. Their yields were found to decrease both when moving from 1,3-H2- to 1,3-Alk2-4,5- dihydroxy- imidazolidin-2-ones and when increasing the size of the substituent at the second N atom in the starting acetylaminoethylurea. The higher yields were achieved with 4,5-diphenyl-4,5- dihydroxyimidazolidin-2-one as the starting compound. 2-(2-Acetylaminoethyl)-4-methylgly- coluril exhibits nootropic activity.

Various ethylenediamine derivatives have been incorporated into the nitrogen substituent of certain short-acting (aryloxy)propanolamine systems that contain esters on their aryl functions.Although several of these compounds showed durations of action comparable to their prototypes, most of the nitrogen substituents significantly prolonged the duration of β-adrenergic blockade.Similarly, while one of the compounds showed appreciable cardioselectivity in vitro, generally, little enhancement of cardioselectivity was obtained.A brief discussion of structure-activity relationships observed for the ethylenediamine derivatives is presented.
