2-(4-Methoxyphenyl)-5-(4-methylpent-3-enyl)-2,3,3a,4,7,7a-hexahydro-1H-isoindole-1,3-dione

D. E. Lynch and I. McClenaghan

Abstract: The structure of the title compound, C₂₁H₂₅NO₃, comprises a U-shaped molecule with two disordered atoms in the pentene chain. The two components of the two disordered alkane C atoms exist with unequal partial occupancies of 0.70 and 0.30. The dihedral angle between the planar imide ring [r.m.s. deviation 0.038  (3)  Å] and the phenyl ring is 62.56  (14)°. C-HO close contacts are observed from two different aromatic C atoms to the two oxo O atoms.
