Atom-economic synthesis of 4-pyrones from diynones and water

Transition-metal-free synthesis of 4-pyrones via TfOH-promoted nucleophilic addition/cyclization of diynones and water has been developed. This transformation is simple, atom economical and environmentally benign, providing rapid and efficient access to s

Bronsted acid catalyzed and NIS-promoted cyclization of diynones: Selective synthesis of 4-pyrone, 4-pyridone, and 3-pyrrolone derivatives

Bronsted acid catalyzed tandem cyclization was found to be highly effective for the preparation of a series of polysubstituted 4-pyrones from diynones (yield up to 99%). 4-Pyridone and 3-pyrrolone derivatives were also selectively synthesized by employing NIS and/or Bronsted acid. NIS as an electrophilic reagent could promote these reactions efficiently and rapidly under very mild reaction conditions.

Thermal Cycloaddition of Aroylketene to 1-Aryl-1-trimethylsilyloxyethylene: A Simple Synthesis of 2,6-Diaryl-4H-pyran-4-one

Aroylketene (2) generated by pyrolytic decarbonylation of 5-aryl-2,3-dihydro-2,3-furandione (1) reacted with 1-aryl-1-trimethylsilyloxyethylene (3) in a regioselective manner to give 2,6-diaryl-4H-pyran-4-one (5) and/or 1,5-diarylpentane-1,3,5-trione (6).

A New Synthesis of 3-Nitro-4H-pyran-4-ones from Acetylenic β-Diketones

A new method for the synthesis of 3-nitro-4H-pyran-4-ones is described involving nitration of acetylenic β-diketones.The 3-nitropyrones are converted into the corresponding 4-thiones which afford the respective 3-nitrooximes and N-methyl-4-thiopyridones o
