(E)-(3-methyl-2,3-dihydrobenzofuran-3-yl)but-2-enones has been developed through a Pd-catalyzed one-pot cascade process involving two sequential Heck reactions, that is, an intramolecular Heck reaction of olefin-tethered aryl iodides and an intermolecular Heck reaction with substituted styrenes and α,β-unsaturated ketones. As a result, a series of desired products were obtained in moderate to good yields and
已开发出一种有效的方法来官能化 ( E )-3-cinnamyl-3-methyl-2,3-dihydrobenzofurans 和 ( E )-(3-methyl-2,3-dihydrobenzofuran-3-yl)but-2-enones通过 Pd 催化的一锅级联过程,涉及两个连续的 Heck 反应,即烯烃束缚芳基
碘化物的分子内 Heck 反应和与取代的
