Abstract An efficient synthesis of polysubstituted dihydropyrrol-2-one derivatives via one-pot four-component domino reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of zirconium tetrachloride (ZrCl4) is described. The presented methodology offers several advantages such as simplicity of operation, good to high yields, short reaction times, inexpensive and readily
