Base-induced intramolecular cyclization of novel (4-aryl-2,4-dioxobutyl)methylphenylsulfonium salts prepared from the commercially available 1-arylethanone by a cost-effective process is described in this paper. The reaction was completed within 10 min to produce a family of 2-unsubstituted 5-aryl-3(2H)-furanones in excellent yield. This procedure is simple, and can be carried out under mild conditions and an ambient atmosphere.

Cyclodehydration of γ-hydroxy-β-enaminoketones derived from 5-substituted-3-isoxazolemethanols leads to 3(2H)furanones or 3(2H)iminofuranes depending on the substitution pattern and on the reaction conditions.
