Crystal structures of sulochrin derivatives

Article abstract of DOI:10.1248/cpb.46.1929

The crystal structures of sulochrin derivatives, sulochrin triacetate (2) and sulochrin 4-(4'-bromobenzoate) (3), were determined, Triacetyl derivative 2 was in a conformation where the planes of two aromatic rings and the central carbonyl plane were all oblique to each other. Compound 3 was in a conformation where ring B and the central carbonyl planes were co-planar and crossed at a right angle to the ring A plane, suggesting the effect of substituents at ortho positions on conformation of tetra ortho substituted benzophenones.
