A convenient synthesis of 3-substituted-5,5-dimethyltetrahydro-2-benzopyran-8-ones through hetero-Diels-Alder reaction

Article abstract of DOI:10.1080/00397919208021081

2-Formyl-4,4-dimethylcyclohexa-2,5-dien-1-one undergoes hetero-Diels-Alder reactions with electron-rich olefins to yield 3-substituted-5,5-dimethyl-3,4,4a,5-tetrahydro-8H-2-benzopyrane-8- ones. The endo addition is favoured.
