Furan-2(5H)-one derivatives have been synthesized by a simple, efficient, one-pot, three-component condensation of anilines, dimethylacetylenedicarboxylate, and aromatic aldehydes in the presence of a catalytic amount of tin(II) chloride in excellent yields.

An efficient and high-yielding protocol using nano-ZnO (50–100 nm) as an efficient heterogeneous catalyst for one-pot three-component synthesis of pharmacologically significant furanone derivatives by the condensation of aromatic aldehyde, amine and dimethylacetylenedicarboxylate has been developed. Since the catalyst is heterogeneous, it can be easily separated and recycled several times without much
