A new route to the optically pure spiro[cyclopentane-1,1′-indan]-2,5-dione system, which is supposed to be valuable for the asymmetric synthesis of optically active fredericamycin A, has been developed through a stereospecific rearrangement of the trans-α,β-epoxy acylates in the tetrahydrobenz[e]indan systems.
