Asymmetric Organocatalytic Synthesis of Sulfone‐Containing (Dihydro)pyrans via Formal (4 + 2)‐Cycloadditions of Allenylsulfones or Propargylsulfones and Michael Acceptors

open access: yesChemCatChem, EarlyView.
Asymmetric isochalcogenourea‐catalyzed cycloadditions of allenylsulfones and propargylsulfones with Michael acceptors allow for the highly selective syntheses of sulfone‐containing dihydropyrans and 4H‐pyrans. Abstract The activation of electron‐poor allenes with Lewis's base catalysts allows for unique transformations and chiral isochalcogenoureas ...
