Structure of 2-(2-Hydroxyethyl)-1-p-tolyl-4,5,6,7-tetrahydro-3(1H)-isoindolone

Article abstract of DOI:10.1107/S0108270193004238

The flexible cyclohexene ring of the isoindole moiety, as indicated by the positional disorder of the C5 and C6 atoms, assumes two kinds of half-chair conformation, ⁴H5 or ⁵H4, at an equilibrium ratio of 68:32.The planar pyrrole ring forms dihedral angles of 76.45(3) and 86.21(9) deg with the best planes through the 1-p-tolyl and 2-ethyl moieties, respectively.Both moieties occupy a cis position with respect to the pyrrole ring .
