An enantioselective redox-relay oxidative Heck arylation of 1,1-disubstituted alkenes to construct β-stereocenters was developed using a new pyridyl-oxazoline ligand. Various 1,2-diaryl carbonyl compounds were readily obtained in moderate yield and good to excellent enantioselectivity. Additionally, analysis of the reaction outcomes using multidimensional correlations revealed that enantioselectivity
使用新的吡啶基恶唑啉配体开发了 1,1-二取代烯烃的对映选择性氧化还原中继氧化 Heck 芳基化以构建 β-立构中心。各种 1,2-二芳基羰基化合物很容易以中等收率和良好至优异的对映选择性获得。此外,使用多维相关性对反应结果的分析表明,对映选择性与 1,1-二取代烯醇的特定电子特征和配体的极化程度有关。
