Knoevenagel condensation of various aromatic aldehydes with 2,4-thiazolidinedione has been carried out in polyethylene glycol-300. The reactions were carried out at moderate temperature with very simple isolation procedure and with better yields.

A convenient one-pot condensation route has been developed for obtaining 5-[(2-(piperidin-1-yl) quinolin-3-yl) methylene]-2,4-thiazolidinediones using multicomponents, 2-chloro-3-formyl quinolines, piperidine, 2,4-thiazolidinedione and safer medium/mediator, polyethylene glycol-400.
