An enantioselective photooxidative Mannich reaction of dihydroquinoxalinones with ketones by the merger of organophotoredox and asymmetric organocatalysis is described. This protocol features very mild reaction conditions using simple and cheap catalysts (Eosin Y and (S)-Proline) for the synthesis of chiral quinoxaline derivatives with good to high yields (up to 94%) and excellent enantioselectivities

A series of substituted5-[4-[2-(6,7-dimethyl-1,2,3,4-tetrahydro-2-oxo-4-quinoxalinyl)ethoxy]phenyl]methy lene]thiazolidine-2,4-diones were synthesized and their euglycemic and hypolipidemic activities were investigated in Wistar male rats. Based on the in vivo data in rats, compound 4a was identified as a potent euglycemic and hypolipidemic agent.
