Herein, we report an asymmetric intermolecular Heck-type reaction of acyclic alkenes by using a palladium-pyridinyl oxazoline diacetate complex under oxidative palladium(II) catalysis conditions. A premade palladium-ligand complex afforded higher enantioselectivities than a corresponding premixed palladium-ligand system, while offering enhanced asymmetric induction when compared to known intermolecular
在这里,我们通过在氧化钯(II)催化条件下使用钯-吡啶基恶唑啉二乙酸酯络合物报告无环烯烃的不对称分子间Heck型反应。与已知的分子间Heck型方案相比,预制的钯-配体配合物比相应的预混合的钯-配体体系具有更高的对映选择性,同时提供增强的不对称诱导性。
