With the treatment of tributylphosphine and base, alkynoates, aromatic aldehydes and acyl chlorides readily undergo a four-component cascade annulation reaction, giving tri-or tetra-substituted furans in moderate yields. The reaction presumably proceeds through an intramolecular Wittig reaction step of the in situ generated phosphorus ylide intermediate. The annulation reaction features mild reaction conditions and broad substrate scope, and accordingly constitutes a facile and new synthetic method of polysubstituted furans.

Key words: furans, synthesis, phosphines, multicomponent reactions, Wittig reaction
