The usefulness of flavin-based aerial photooxidation in esterification underMitsunobu reaction conditions was demonstrated, providing aerial dialkyl azodicarboxylate recycling/generation from the corresponding dialkyl hydrazine dicarboxylate. Simultaneously, activation of triphenylphosphine (Ph3P) by photoinduced electron transfer from flavin allows azo-reagent-free esterification. An optimized system

An N(5)‐flavin adduct was utilized in a catalytic Mitsunobureaction with triphenylphosphane (triphenylphosphine), in which flavin acts as a Mitsunobu reagent instead of dialkyl azodicarboxylate. Flavin is used in a catalytic amount after regeneration by dioxygen.
