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-

## Abstract The transition structures of the heteroโ€Dielsโ€Alder reaction of (__E__)โ€ and (__Z__)โ€1โ€azaโ€1,3โ€butadiene (8 and 11) were studied by means of ab initio (UHF/6โ€31+G\* and RHF/6โ€31+G\*) and semiempirical (AM1, PM3) methods. The energy surface of the title reaction was calculated with AM1/C
