概要

• 論文の詳細を見る

• Pericyclic reactions of 2,5-bis(methoxycarbonyl)-3,4-diphenylcyclopentadienone (Ia) with nonconjugated dienes (IIa-g) were investigated. The cyclopentadienone (Ia) reacted readily with IIa-g to give [4+2]π cycloadducts (IIIa-g) that lost carbon monoxide to afford intramolecular double Diels-Alder adducts (Va-g) on heating above the melting points. The structures of these adducts were determined from spectral evidence. The stability of the cycloadducts between twistene and isotwistene type compounds is discussed on the basis of molecular mechanics calculation data.
