A highly enantioselective synthesis of target-relevant oxabicyclic systems is reported. The synthesis involves a sequence of two formal oxa-Diels–Alder reactions between a wide variety of achiral dendralenes and a carbonyl dienophile, proceeding with the generation of two new rings, four new covalent bonds and up to four new stereocenters.
