The first total synthesis of (+)-astrophylline (2) has been achieved, starting from readily available enantiomerically pure (+)-(1R,4S)-4-hydroxycyclopent-2-enyl acetate (11). A novel ruthenium-catalyzedring-closingring-openingring-closingmetathesis of carbocyclic olefins of general type 5 was the key step, providing the stereochemically well-defined bis-piperidyl skeleton of the target molecule
