A series of novel hybrid phosphorus ligands were designed and applied to the Rh-catalyzed enantioselective anti-Markovnikov hydroformylation of unfunctionalized 1,1-disubstituted alkenes. By employing the new catalyst, linear aldehydes with β-chirality can be prepared with high yields and enantioselectivities under mild conditions. Furthermore, catalyst loading as low as 0.05 mol % furnished the desired product in good yield and undiminished selectivity, demonstrating the efficiency of this transformation in large-scale synthesis.
一系列新型杂化磷配体被设计并应用于 Rh 催化的非官能化 1,1-二取代烯烃的对映选择性反马氏加成反应。通过使用新型催化剂，在温和条件下可以高收率和对映选择性地制备具有β手性的直链醛。此外，在 0.05 mol%的低催化剂负载量下，即可得到所需产物，产率和选择性均未降低，这表明该转化在大规模合成中具有高效性。
