amide bond formation by way of a continuous‐flow photochemicalrearrangement of nitrones was described (see scheme). Simple aryl‐alkyl amide bonds as well as complex peptide bonds were constructed efficiently with a residence time less than 20 minutes. A tetrapeptide was synthesized in this way and the method could be applied to peptidefragmentcoupling.
The TEMPO oxidation method is successfully applied to preparation of variously protected, opticallyactive α-amino aldehydes without racemization and in very good yield.
