| Research Abstract |
Monosubstituted conjugated enynes were found to undergo [4+2] homodimerization smoothly in the presence of palladium catalyst to give 4, α-and 2,6-disubstituted styrene derivatives. Analogous cross-cycloaddition of conjugated enynes and diynes was also developed to afford a variety of polysubstituted benzenes, including phenol and aniline derivatives. Alkynes and diynes in the presence of a palladium catalyst underwent novel formal [2+2+2] sequential cyclotrimerization to afford multifunctional benzenes in one step with high degrees of regio- and chemoselectivities. Mechanism of these novel transformations was proposed.
