Abstract : Development of greener methodologies in synthetic organic chemistry has brought awareness in recent decades due to the ecological performance of green solvent media and catalytic 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 ABSTRACT: SYNOPSIS We carried out the peptide bond formation reaction in ionic liquids in the presence of a coupling reagent at room temperature, in the absence of an external base, affording dipeptides in good to excellent yields.

Asymmetric induction during the aminolysis of 5(4H)-oxazolones from N-benzoyl amino acids was investigated using a series of amino acid esters as amine nucleophiles.The reaction of the oxazolone from N-benzoyl-DL-t-leucine with methyl L-prolinate was found to produce the diastereomeric D-L isomer, almost specifically, under appropriate conditions.
