neolignan from was converted to a dibenzocyclooctadiene derivative by using two new reagents. The compound was further functionalized by the use of DDQ to mono- and dialcohols. Acid treatment of the monoalcohols led to oxidative demethylenation. The diols were converted to an epoxide and other rearranged products. The stereochemistry of the mono- and dialcohols was established based on nmr and cd spectral
