title: A cycloaddition product of a chiral maleimide: 4-{(3aS*,6aS*)-4,6-dioxo-1-phenyl-5-[(1R)-1-phenyl-ethyl]-1,3a,4,5,6,6a-hexa-hydro-pyrrolo[3,4-c]pyrazol-3-yl}phenyl acetate.
abstract: In the title mol-ecule, C(27)H(23)N(3)O(4), the two central five-membered rings form a dihedral angle of 63.66 (4)°. The absolute configuration was determined by analysis of Bijvoet pairs based on resonant scattering of light atoms, yielding a Hooft parameter y = -0.10 (7).
