Metal‐Free C3 Hydroxylation of Quinoxalin‐2(1H)‐ones in Water

A practical protocol for the preparation of quinoxaline‐2,3(1H,4H)‐diones through direct C(sp2)−H hydroxylation of quinoxalin‐2(1H)‐ones in recyclable DL‐α‐Tocopherol methoxypolyethylene glycol succinate solution (2 wt% in water) (TPGS‐750‐M/H2O) was developed. The target products were exclusively g...

Summary:A practical protocol for the preparation of quinoxaline‐2,3(1H,4H)‐diones through direct C(sp2)−H hydroxylation of quinoxalin‐2(1H)‐ones in recyclable DL‐α‐Tocopherol methoxypolyethylene glycol succinate solution (2 wt% in water) (TPGS‐750‐M/H2O) was developed. The target products were exclusively generated and could be collected through extraction and recrystallization.
