(2S,4′R,5′R)-(E)-tert-Butyl 2-acetyl-2-(2-oxo-5-phenyl-1,3-dioxolan-4-ylmeth­yl)-5-phenyl­pent-4-enoate

The title compound, C(27)H(30)O(6), was prepared by monodihydroxy­lation of the bis-olefin (E,E)-tert-butyl 2-acetyl-2-cinnamyl-5-phenyl­pent-4-enoate using standard Sharpless asymmetric dihydroxy­lation conditions, followed by treatment with 1,1′-carbonyl diimidazole. In the crystal structure, the phenyl rings form an intra­molecular edge-to-face C—H⋯π contact with an inter­planar angle of 56.4° and a H⋯centroid distance of 3.03 Å.
