Regiodivergent Hydration–Cyclization of Diynones under Gold Catalysis
Skipped diynones, efficiently prepared from biomass-derived ethyl lactate, undergo a tandem hydration− oxacyclization reaction under gold(I) catalysis. Reaction conditions have been developed for a switchable process that allows selective access to 4-pyrones or 3(2H)-furanones from the same starting...

| Summary: | Skipped diynones, efficiently prepared from biomass-derived ethyl lactate, undergo a tandem hydration− oxacyclization reaction under gold(I) catalysis. 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. |
