ChemInform Abstract: (4 + 2)Cycloaddition Reaction of Substituted 2‐Pyrones with Maleimides and Stability of the Adducts.
View through CrossRef
AbstractDiels‐Alder reaction of the pyrones (I) with the maleimides (II) results in the formation of the 1:1‐endo adducts (III) or the decarboxylated 1:2‐endo‐endo adducts (IV) or a mixture of both depending on the electronic structure of the pyrones, the reaction time, and the reflux temperature.
