and environmentally-benign protocol for the synthesis of biologically important oxindole derivatives in high yields has been demonstrated by employing isatins as carbonylcompound surrogates in a Passerini reaction carried out undersolvent-freeconditions. Moreover, electron-deficient phenols can also be used as the acid component in this reaction. In addition, the synthetic utility of the present methodology

Passerini three-component cascade reactions in deep eutectic solvent: an environmentally benign and rapid system for the synthesis of α-acyloxyamides
A greener synthesis of α-acyloxyamides was achieved by one-pot three component cascade Passerini reactions in a deep eutectic solvent (DES). Reactions proceeded rapidly and afforded the corresponding α-acyloxyamides by a variety of aldehydes, acids and isocyanides in excellent yields. The DES has the advantages of easy workup, high yield, and an environmentally benign and, moreover, shortened time as the greatest exclusivity of this system compared with previously reported methods.
