A broad range of highly functional furans can be efficiently generated from Michael acceptors, tributylphosphine, and acyl chlorides in one step at room temperature in good yields. The reaction was proposed to proceed via intramolecular Wittig-type reactions, using phosphorus ylides as intermediates.
