(11SR,15SR)-9,10,11,15-Tetrahydro-9-[(1SR)-1-methoxyethyl]-9,10-[3',4']furanoanthracene-12,14-dione

W. Clegg and R. W. Harrington

Abstract: The title compound, C₂₁H₁₈O₄, has a molecular structure with a rigid polycyclic nucleus, in which an acid anhydride ring bridges the two CH positions of the central ring of anthracene. The 1-methoxyethyl substituent, by contrast, has conformational freedom and adopts an orientation minimizing steric and electronic repulsions with the anhydride group.
