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

A simple and efficient synthesis of N-substituted 5-arylidene rhodanines has been developed via aldol condensation of N-substituted rhodanines with aromatic aldehydes using L-proline as the catalyst in water at room temperature. The attractive features of this protocol are simple experimental procedures, cleaner reactions, column free, high yield and avoid the use of toxic solvents.
