The first asymmetric hydrogenation of acyclic tetrasubstituted α,β-unsaturated amides has been achieved by using Rh/DuanPhos complex as a catalyst, delivering chiral β-amino amides with two contiguous chiral centers in excellent yields and high enantioselectivities (up to 99% yield, 96% ee), which provides efficient and concise access to valuable β-amino amide derivatives. The gram-scale reaction and
通过使用 Rh/DuanPhos 络合物作为催化剂,首次实现了无环四取代 α,β-不饱和酰胺的不对称氢化,以优异的产率和高对映选择性(产率高达 99%, 96% ee),提供了高效、简洁地获取有价值的 β-氨基酰胺衍生物的方法。克级反应以及β-氨基酰胺向β-氨基酸和β-氨基氰化物的有效转化证明了该方法的实用性。
