(3aSR,9aSR)-3a,4,9,9a-Tetrahydro-4-[(1SR)-1-methoxyethyl]-2-methyl-4,9-[1',2']benzeno-1H-benzo[f]isoindole-1,3-(2H)-dione

Abstract: The title compound, C₂₂H₂₁NO₃, has a molecular structure with a rigid polycyclic nucleus, in which a carboxamide 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 carboxamide group.
