Synthesis of sulfur-containing heterocycles: Spiropyrimidinetriones, thioxopyrimidinediones, pyrazolidinediones, and isoxazolidinediones-Part II

1-Aroyl-2-styrylsulfonylethene is the precursor for 4,4-dimethoxycarbonyl-2′,5-diaryl-3-(1′,3′-dioxolano)-1-thia-1 ,1-dioxide (4, which is the key intermediate for the synthesis of 7-aroyl-11-aryl-2,4-diazaspiro-[5,5]undecane-1,3,5-trione-9-thia-9,9-dioxi
