Ethyl 3-phenyl-1,3-butadiene-2-carboxylate derivatives (IIa-d) were prepared from dimethylsulfoxonium 3-ethoxycarbonyl-2-phenylallylide by the treatment with triethylamine. These structures were determined by nuclear magnetic resonance spectra, Diels-Alder reaction with tetracyanoethylene and other chemical evidence. The mechanistic assumption for the formation of the butadiene derivatives from sulfoxonium ylides was given. Dimethylsulfoxonium N, 4-diphenyl-3,4-dehydropiperidino-3,6-dion-5-ylide derivatives (XIa-c) were obtained from dimethylsulfoxonium 1-phenylcarbamoyl-3-ethoxycarbonyl-2-phenylallylide (Xa-c) by the treatment with sodium ethoxide.
