Phase-dependent antioxidant behavior in a synthetic C-α-glucogallin analogue library by photoredox-mediated α-ketonylation.

Phenolic acid glycosyl esters like glucogallins are promising antioxidants but are often limited by hydrolytically labile O-glycosidic linkages. Here, twelve C-α-glucogallin analogues were synthesized in six steps from commercial peracylated sugars by combining four monosaccharides with three plant-derived phenolic aci...
