摘要: A mild and efficient method for the one-pot synthesis of substituted dihydropyrrol-2-one derivatives is described via four-component domino reaction amines, dialkyl acetylenedicarboxyaltes formaldehyde in presence 1-methyl-2-oxopyrrolidinium hydrogen sulfate ([Hpyro][HSO4]) as ionic liquid catalyst. This facile approach proceeded smoothly good to high yields pure products are separated from mixture by simple filtration.
