Abstract
Double stereocontrol is achieved in the Pd‐catalyzed cyclization of Δ^3‐oxonene precursors (see reactions outlined below). The configuration of the olefinic double bond and of the allylic carbon center α to the ether oxygen atom is dictated by the configuration of the double bond in the starting compound (E/Z), the Pd ligand (dppe = Ph_2PCH_2CH_2PPh_2), and the reaction time.
