Abstract
A synthesis of epoxyquinone natural product cytosporin D from the readily available Diels-Alder adduct of cyclopentadiene and 2-prenyl-p-benzoquinone, has been accomplished. This approach leverages the stereochemical predisposition of the norbornyl-fused systems towards convex face reactivity as an enabler for the stereoselective construction of the pyran ring.
