A simple, efficient, and environmentally friendly approach has been developed for the synthesis of peptides in aqueous medium. In this work, peptides are easily synthesized in water extract of banana (WEB)/ethylene glycol and without using external base under mild condition.

systems. Here, we carried out the peptide bond formation reaction in one of the environmentally secure solvents, ‘ionic liquids’ in the presence of coupling reagent and in the absence of external base at room temperature, affording dipeptides in good to excellent yields. GRAPHICAL ABSTRACTSYNOPSIS We carried out the peptide bond formation reaction in ionic liquids in the presence of a coupling reagent
A new type of stable amides is synthesized, which can react with various nucleophiles like acyl chlorides under light irradiation. This controllable switched-on reactivity hinges on a rational-designed photo-activatable masked acyl donor reagent.
