Synthesis of nonracemic 3-deoxyschweinfurthin B has been accomplished through a synthetic sequence including a key cascade cyclization of an epoxy olefin. The intermediate epoxide could be prepared as a single enantiomer through an AD-mix-α (or AD-mix-β) oxidation, and the stereochemistry of the epoxide has been shown to control formation of the two additional stereogenic centers created through the
