A one-pot self regulated approach for the synthesis of amides/peptides based on two reduction–oxidation (redox) reactions has been described. The primary and secondary amides/peptides are made by using azidotrimethylsilane and alkyl azides/α-azido acid derivatives respectively as the direct source of amine components. Benzeneselenol, generated in the reaction medium during carboxyl activation, has

A new and highly efficient one-pot self-regulated approach to amide/ peptide synthesis has been developed based on two redox reactions using azide as a latent amine component. For the first time, selenophenol, generated in situ has been found to be an effective reducing agent for the conversion of azides to amines.
