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
设计了一系列新型杂化磷配体,并将其应用于未官能化 1,1-二取代烯烃的 Rh 催化的对映选择性抗马尔科夫尼科夫加氢甲酰化反应。通过使用这种新型催化剂,可以在温和的条件下以高收率和对映选择性制备具有β-手性的线性醛。此外,低至 0.05 mol% 的催化剂负载量以良好的收率和未降低的选择性提供了所需的产品,证明了这种转化在大规模合成中的效率。
