for the synthesis of N-substituted-5-arylidene-rhodanines has been reported in high yield via [bmim]OAc-catalyzed one-pot four-component domino Knoevenagel condensation of primary amine, carbon disulfide, ethyl chloroacetate, and aromatic aldehyde under neat condition. The catalytic role of [bmim]OAc is due to the acidic nature of C-2 hydrogen of bmim cation and the basic nature of acetate anion in

ABSTRACT In this study, a one-pot, solvent-free stereoselective reaction was started between primary amines, carbon disulfide, ethyl bromoacetate, and furan derivatives derived from sugars at room temperature, which was completed within 10 min to produce rhodanine–furan hybrid molecules in good to high yields. The presence of the chloromethyl group in products derived from chloromethylfurfural (CMF)
