products, preferably using a catalytic method, is of great interest and importance in both organic synthesis and drug discovery. Herein, we report an unprecedented stereodivergent AH of di-substituted quinoxalines via Mn catalysis, furnishing cis- and rarely accessed trans-chiral tetrahydroquinoxalines (THQs) with high levels of diastereo- and enantioselectivity. This transformation features excellent functional
