- 論文の詳細を見る
Cycloaddition of 2,5-disubstituted-3,4-diphenylcyclopentadienone with acyclic conjugated dienes gave the endo [4+2]π cycloadducts, which then underwent [3,3]-sigmatropic rearrangement to give the corresponding endo [2+4]π cycloadduct on heating at 110℃. Pyrolysis of the endo [4+2]π cycloadducts at 170℃ resulted in decarbonylation to give the double Diels-Alder adduct. The sequential pericyclic reaction behavior is discussed on the basis of X-ray diffraction analyses and molecular orbital calculation data.
