Abstract: The photocycloaddition of enantiopure bis-dihydropyridone 4 provided a single cycloadduct in high yield. Treatment of the cycloadduct with SmI2 effected ring opening and intramolecular aldol addition to give pentacyclic beta-hydroxyketone 7. (C) 1997 Elsevier Science Ltd. All rights reserved.
