A highly efficient and enantioselective hydrogenation of β-aryloxy/alkoxy cinnamic nitriles and esters under mild conditions has been realized by using a rhodium catalyst with a chiral f-spiroPhos ligand. The method provides efficient access to the asymmetric synthesis of a variety of chiral β-oxy-functionalized nitriles and esters with excellent enantioselectivities (up to 99.9% ee) and high turnover
通过使用具有手性f-spiroPhos配体的铑催化剂,已经实现了温和条件下β-芳氧基/烷氧基肉桂腈和酯的高效,对映选择性氢化。该方法可以有效地获得具有出色对映选择性(高达99.9%ee)和高周转率(TON高达50000)的各种手性β-氧基官能化的腈和酯的不对称合成。该方法也已成功地应用于手性药物尼索西汀的简洁实用合成。
