We report that α-acyloxy-β,γ-unsaturated cyclopentenones were used as starting substrates to make various trisubstituted cyclopentadienones. The substrates are easily available in one step from our previously developed protocol, and the potential of this cyclopentadienone formation method was demonstrated in a series of Diels–Alder reactions, forming dimerization products, dimethyl phthalate derivatives
我们报道α-酰氧基-β,γ-不饱和环戊烯酮被用作起始底物以制备各种三取代的环戊二烯酮。可以轻松地从我们先前开发的方案中一步获得底物,这种环戊二烯酮形成方法的潜力已在一系列Diels-Alder反应,形成二聚产物,邻苯二甲酸二甲酯衍生物和聚芳基苯化合物的过程中得到了证明。
