摘要

At 2.5 mol % loadings using reaction temperatures between 30-55 degrees C, ortho-functionalized diaryl diselenides are highly effective organocatalytic oxidants for aerobic redox dehydrative amidic and peptidic bond formation using triethyl phosphite as a simple terminal reductant. This simple-to-perform organocatalytic reaction relies on the ability of selenols to react directly with dioxygen in air without recourse to metal catalysts. It represents an important step toward the development of a general, economical, and benign catalytic redox dehydration protocol.
