| Abstract: | Condensation of 1-alkyl-4,5-dihydroxyimidazolidine-2-thiones (monoalkylthiourea-glyoxal cyclic adducts) with 1,3-dialkylureas affords novel 1,4,6-trialkylsemithio- glycolurils having non-substituted NH group linked to C=S function. Such compounds can be accessed in two-stage one-pot reaction sequence from alkylthioureas and glyoxal followed by treatment of the resulting adduct with 1,3-dialkylureas |
