摘要

In model studies 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 alpha- pyones. The incorporation of the key bridge methyl group and subsequent control of its stereochemistry is also outlined.
