Popis:	It has been found for the first time that 2-thioxo-4-quinazolone in the presence of acid catalysts in dimethyl sulfoxide is converted to8H,15H-1, 2, 4-thiadiazolo[3, 2-b:5, 4-b′]diquinazoline-8,15-done. The reaction proceeds via oxidative cyclocondensation. The formation of this structure in preference to five other proposed isomers is substantiated using quantum-chemical methods.
