1-Benzyldimethylsilyl-4-phenylthio-1,3-butadiene (L), prepared by hydrosilation of propargyl alcohol, oxidation and followed by Wittig-Horner reaction, underwent Diels-Alder reaction with methyl methacrylate. The adduct after oxidation to the sulfone when treated with fluoride gave 5-carbomethoxy-5-
