A short, enantioselective synthesis of (−)-pentalenene is described. Catalytic enantioselective cyclopropenation with (R,R)-Rh2(OAc)(DPTI)3 was used to set the absolute stereochemistry, and an intramolecular Pauson−Khand reaction of the resulting cyclopropenyne was used to establish the quaternary center.
