ester is aryl-tethered to an allylic amine, by catalytic intramolecular ammoniumylide generation and [2,3] rearrangement. When the aryl tether is sufficiently electron-deficient, direct coupling of the rearrangement product with a hindered amino acid ester to give a dipeptide is possible, and ammoniumylide generation, rearrangement and peptide coupling can be accomplished in a one-pot fashion.
