Reaction conditions have been developed for a switchable process that allows selective access to 4-pyrones or 3(2H)-furanones from the same starting diynones. Further application of this methodology in the total synthesis of polyporapyranone B was demonstrated. 1523-7060 http://hdl.handle.net/10259/5533 10.1021/acs.orglett.0c02892 1523-7052 Hydrocarbons Cyclization Mixtures Catalysts Selectivity Regiodivergent Hydration–Cyclization of Diynones under Gold Catalysis
