Graphical Abstract

The non-noble metal-catalyzed asymmetric hydrogenation of N-heteroaromatics, quinolines, has been realized by using a well-defined chiral pincer manganese catalyst, with up to 97 % ee and 3840 TON.

Abstract

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.
