Rhodium-catalyzed asymmetric anti-Markovnikov hydroformylation of α-substituted acrylates/acrylamides has been developed. By employing the Rh/(S,S)-DTBM-YanPhos complex, a series of β-chiral linear aldehydes were obtained in high yields (up to 94% yield) and high enantioselectivities (up to 96% ee). The utility of this methodology is demonstrated by a gram-scale reaction and a concise synthetic route
已经开发出铑催化的α-取代的丙烯酸酯/丙烯酰胺的不对称抗马尔科夫尼科夫加氢甲酰化反应。通过使用Rh /(S,S)-DTBM-YanPhos络合物,可以高收率(最高94%收率)和高对映选择性(最高96%ee)获得一系列β-手性线性醛。该方法的实用性通过克级反应和简明的合成方法制备,证明了手性γ-丁内酯的合成。
