of unsymmetrical 1,5-diarylpenta-1,4-dien-3-ones with thiobarbituric acid 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 thiobarbituric acid with the corresponding aromatic aldehydes and 4-arylbut-3-en-2-ones.
不对称的1,5-二芳基-1,4-二-3-酮与硫代巴比妥酸的碳环化反应提供了以前未知的7,11-二芳基-3-thioxo-2,4-二氮杂螺[5.5]十一烷-1,5,9-具有高区域选择性和立体选择性的三酮 还通过硫代巴比妥酸与相应的芳族醛和4-芳基丁-3-烯-2-酮的三组分缩合来合成相同的螺环化合物。
