We report a Pd-catalyzed intermolecular hydrophosphinylation of 1,3-dienes to afford chiral allylic phosphine oxides. Commodity dienes and air stable phosphine oxides couple to generate organophosphorus building blocks with high enantio- and regiocontrol. This method constitutes the first asymmetric hydrophosphinylation of dienes.
我们报告了一种 Pd 催化的 1,3-二烯的分子间氢膦化反应,得到手性烯丙基膦氧化物。商品二烯和空气稳定的磷氧化物偶联,以高对映选择性和区域选择性生成有机磷砌块。该方法构成了首例不对称二烯氢膦化反应。
