B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub>: A New Class of Strong and Bulky Lewis Acid for <i>Exo</i>-Selective Intermolecular Diels–Alder Reactions of Unreactive Acyclic Dienes with α,β-Enals
Lewisacid B(C6F5)3 catalyzed the Diels–Alderreactions of multisubstituted open-chain dienes and α,β-enals to afford the desired products with high exo-selectivities are reported. The substituent effect of the dienes and dienophiles on the product’s stereoselectivity was thoroughly investigated, and it was found that most of the desired exo-Diels–Alder products could be obtained in good yields and
据报道,路易斯酸B(C 6 F 5)3催化多取代的开链二烯和α,β-烯醛的Diels-Alder反应,可提供所需的具有高外选择性的产物。彻底研究了二烯和亲二烯体对产物立体选择性的取代作用,发现大多数所需的exo -Diels-Alder产品可以高收率和高exo-立体选择性获得。
