| abstract | Novel compounds of the general formula II <FORM:1095866/C2/1> wherein R represents a hydrogen atom or an alkyl, substituted alkyl, aryl, substituted aryl, acyl, aroyl or a nitro group; R1 and R11 may be the same or different and represent hydrogen atoms or alkyl, hydroxyl, alkoxy, substituted alkoxy, aryloxy, substituted aryloxy, acyloxy or aroyloxy groups, and ester and ether derivatives thereof, are prepared by reacting 1 - R - 4 - R11 - 5 - imidazolidin - 2- ones with glyoxal in basic aqueous solution, preferably in molar proportions of 2:1. The substituted imidazolidin-2-one derivative may be prepared in situ from RNHCONH2 and glyoxal (R1 and R11 are hydroxyl groups). Preferred urea derivatives are isopropylurea and N-formylurea; preferred imidazolidin-2-one derivatives are the 4,5-dihydroxy, 4,5-dimethoxy and 1-formyl-4,5-dihydroxy compounds. The glyoxal is preferably in the form of its polymeric monohydrate, and the reaction medium may be rendered basic with Na2CO3 or NaHCO3. |
