hydroformylation and hydroaminomethylation of α-substituted acrylamides is described using 1,3-phosphite-phosphoramidite ligands based on a sugar backbone. A broad scope of chiral aldehydes and amines were afforded in high yields and excellent enantioselectivities (up to 99%). Furthermore, the synthetic potential of this method is demonstrated by the single-step synthesis of the brain imaging molecule RWAY.
使用基于糖主链的1,3-亚磷酸酯-亚磷酰胺配体描述了成功的铑催化α-取代的丙烯酰胺的不对称加氢甲酰化和氢氨基甲基化。以高收率和优异的对映选择性(高达99%)提供了广泛的手性醛和胺。此外,通过脑成像分子RWAY的一步合成证明了该方法的合成潜力。
