Abstract

The new ligands with improved enantioselectivity, recyclable catalytic asymmetric transfer hydrogenation (RCATH) reaction efficiency, and physical properties were synthesized. The new ligands were synthesized and used in RCATH. Among them, ligands 2e and 2f provided high enantioselectivity and reaction efficiency compared to a previously reported ligand 1 used in RCATH.
