Abstract
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 k ey intermediate for the synthesis of 7-aroyl-11-aryl-2,4-diazaspiro[5,5]und ecane-1,3,5-trione-9-thia-9,9-dioxide(10)/3-thioxo-1,5-dione-9-thia-9,9-dio xide (11), 6-aroyl-10-aryl-2,3-diazaspiro[4,5]decane-1,4-dione-8-thia-8,8-d ioxide (12)/2-oxo-3-azaspiro [4,5]decane-1,4-dione-8-thia-8,8-dioxide (13). The new compounds were characterized by IR and H-1 NMR spectral data. (C) 2001 John Wiley & Sons, Inc.
