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 diynones. Further application of this methodology in the total synthesis of polyporapyranone B was demonstrated.

Synthesis of pyran-4-ones from isoxazoles

A synthesis of mono-, di- and tri-substituted pyran-4-ones from isoxazoles is reported. The isoxazoles can be synthesized from readily available starting materials and undergo a reductive cleavage reaction with Mo(CO)6 to generate enamino keton

Thermal addition reaction of aroylketene with ethyl vinyl ether: Aromatic substituent effect on aroylketene reactivity

A series of aroylketenes (2) generated by thermolysis of 5-aryl-2,3-dihydrofuran-2,3-diones (1) reacted with ethyl vinyl ether under a thermal condition to give 2,3-dihydro-4H-pyran-4-ones (3) and/or 4H-pyran-4-ones (4). In this reaction the electron withdrawing substituent (NO2, Cl) introduced into the aryl part enhanced the ketene reactivity (2b-e), while the electron donating one (OMe) did not affect its reactivity (2f-g) in a significant extent. The heteroaroylketenes (2h) and (2i) showed a fairly good reactivity.
