The reactions of sulfamides with 4,5-dihydroxyimidazolidin-2-ones were studied at ambient and high pressure. The previously unknown derivatives of 5(3H)-oxotetrahydro-1H-imidazo-[4,5-c][1,2,5]thiadiazole 2,2-dioxide, viz., sulfo analogs of tetrahydroimidazo[4,5-d]imidazole-2,5-(1H,3H) diones (glycolurils), were synthesized. The structures of some of these compounds were established by X-ray diffraction
