Аннотация:
A new synthetic approach to 2,8-disubstituted 1,5-diphenylglycolurils is based on condensation of 1-(hydroxyalkyl)ureas (ureido alcohols) with tetrahydroimidazooxazolone and tetrahydroimidazooxazinone derivatives which were unexpectedly obtained by acid-catalyzed reaction of ureido alcohols with benzil. An X-ray diffraction study of the supramolecular organization of the obtained compounds revealed the chirality of the crystals of achiral glycoluril molecules.
