چکیده
The title compound, C(27)H(30)O(6), was prepared by monodihydroxy-lation of the bis-olefin (E,E)-tert-butyl 2-acetyl-2-cinnamyl-5-phenyl-pent-4-enoate using standard Sharpless asymmetric dihydroxy-lation conditions, followed by treatment with 1,1'-carbonyl diimidazole. In the crystal structure, the phenyl rings form an intra-molecular edge-to-face C-H⋯π contact with an inter-planar angle of 56.4° and a H⋯centroid distance of 3.03 Å.
