of unsymmetrical 1,5-diarylpenta-1,4-dien-3-ones with thiobarbituricacid afforded previously unknown 7,11-diaryl-3-thioxo-2,4-diazaspiro[5.5]undecane-1,5,9-triones with high regio- and stereoselectivity. The same spiro compounds were also synthesized by three-component condensation of thiobarbituricacid with the corresponding aromaticaldehydes and 4-arylbut-3-en-2-ones.
