Recent Advances in Photocatalytic Transformations of Dioxazolones

As efficient nitrogen radical precursors, dioxazolones have emerged as key intermediates in photocatalytic CN bond construction due to their mild reaction conditions, and generation of only CO 2 as a byproduct. This review summarizes recent advances in the application of dioxazolones in photocatalytic nitrene transfer reactions, with a focus on synthetic methodologies for diverse amides and their derivatives and the mechanistic insights into different catalytic systems. The aim is to provide guidance for developing green and efficient CN, SN, PN, and SN bond formation strategies and to promote the application of photocatalytic nitrene transfer reactions in pharmaceutical and materials science.
