stereogenic centers have been employed as ligands in the copper-catalyzed oxidative coupling of 2-naphthols, resulting in the production of chiral BINOLs in favorable yields and moderate to good enantiomericexcess. This represents the first application of chiral P-based ligands to enable such a transformation. The synthesis of these chiral α-aminophosphonate ligands offers a significant advantage over approaches
具有相邻碳和膦酸酯立体中心的手性 α-氨基膦酸酯已被用作铜催化 2-萘酚氧化偶联的配体,从而以良好的产率和中等至良好的对映体过量生产手性 BINOL。这代表了手性 P 基配体首次应用来实现这种转变。与通常需要复杂的合成工艺来生产手性配体的方法相比,这些手性 α-氨基膦酸酯配体的合成具有显着的优势。
