Asymmetric Ruthenium‐Catalyzed Hydrogenation of 2‐ and 2, 9‐Substituted 1, 10‐Phenanthrolines1. Issue 28 (5th June 2013) - Wang, Tianli
Abstract A 'Phen'atic: The title reaction proceeds in the presence of the chiral cationic ruthenium diamine catalyst (R, R)‐1 (Tf=trifluoromethanesulfonyl, Ts=4‐toluenesulfonyl). Both chiral 1, 2, 3, 4‐tetrahydro‐ and 1, 2, 3, 4, 7, 8, 9, 10‐octahydro‐1, 10‐ phenanthroline derivatives could be obtained in high yields with excellent enantio‐ and diastereoselectivity.
