Tandem Michael-anti-Michael Addition-Mediated Orthogonal Strapping of Diynones: Regioselective Spirocyclopentannulation of Oxindoles and Pyrazolones and DFT Validation

An efficient protocol involving the transformation of sequentially generated recursive anions from heterocyclic precursors to orthogonally strap diynones through one pot transition-metal-free spirocyclopentannulation has been devised, employing oxindoles

Ethyl lactate as a renewable carbonyl source for the synthesis of diynones

Ethyl lactate, a sustainable feedstock, serves as a highly attractive building block for the synthesis of value-added chemicals such as skipped diynones and, after gold-catalyzed transposition, conjugated diynones. Green solvents are involved in all steps

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.
