Visible-light-induced denitrification oxygenation reaction of α-diazoesters with N-hydroxyimides to access α-oxyimido esters has been developed. This reaction provides an efficient approach to synthesize a series of N-hydroxyimides at room temperature in 1,4-dioxane under irradiation of 3W blue LED lamps without any photocatalyst. Interestingly, when tetrahydrofuran (THF) was used as the solvent, structurally diverse α-oxyimido esters could be rapidly and efficiently obtained through a three-component coupling reaction of α-diazoesters, THF, and N-hydroxyimides. The reaction could conduct on a gram scale without a significant loss of reaction efficiency, indicating that this method could serve as a practical protocol to synthesize α-oxyimido esters.

Key words: visible-light, α-diazoester, N-hydroxyphthalimide, α-oxoimide ester
