摘要
Complex intermediates to quassinoids', some optically active and containing many functional groups, were synthesized via a diene-transmissive Diels-Alder strategy. The stereochemistry of the key inter- and intramolecular cycloadditions was controlled by stereodefined groups on the preexisting C ring and on the tether.
