The non‐noble metal‐catalyzed asymmetric hydrogenation of N‐heteroaromatics, quinolines, is reported. A new chiral pincer manganese catalyst showed outstanding catalytic activity in the asymmetric hydrogenation of quinolines, affording high yields and enantioselectivities (up to 97 % ee). A turnover number of 3840 was reached at a low catalyst loading (S/C=4000), which is competitive with the activity of most effective noble metal catalysts for this reaction. The precise regulation of the enantioselectivity were ensured by a π–π interaction.

π-π相互作用使锰催化喹啉不对称加氢**

报道了非贵金属催化的N-杂芳族化合物喹啉的不对称氢化。一种新型手性钳式锰催化剂在喹啉的不对称氢化中表现出出色的催化活性，提供了高收率和对映选择性（高达97％ee）。在低催化剂负载量（S / C = 4000）下，达到了3840的周转率，与该反应中最有效的贵金属催化剂的活性相竞争。对映选择性的精确调节通过π-π相互作用来保证。
