In modelstudies towards the synthesis of harringtonolide, the construction of the tropone moiety via arene cyclopropanation was investigated. The installation of the lactone ring was accomplished by way of a Diels-Alder cycloaddition of various indenones and a-pyones. The incorporation of the key bridge methyl group and subsequent control of its stereochemistry is also outlined.

The Diels-Alder reactions of 5-methoxyindenones with various α-pyrones provide the basis for a new and more efficient approach to the synthesis of the unusual nor-diterpenoid tropone, harringtonolide.
