The mol-ecule of the title compound, C(12)H(16)O(5), has crystallographically imposed mirror symmetry with the mirror plane passing through the endocyclic O atom and the mid-point of the double bond. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains running along the a axis.
متن کاملWestphalen’s diol diacetate: 19(10→5)-abeo-5β-cholest-9-ene-3β,6β-diyl diacetate
THE STRUCTURE OF THE TITLE STEROID [ALTERNATIVE NAME: 3β,6β-diacet-oxy-5β-methyl-19-norcholest-9(10)-ene], C31H50O4, confirms the generally accepted mechanism for the rearrangement of a cholestan-5α-ol derivative reported a century ago by Westphalen. The methyl group at position 10 of the starting material migrates to position 5 in the steroidal nucleus, while a Δ(9) bond is formed, as indicate...
متن کامل(3R,4R)-2,5-Dioxo-1-m-tolyl-3,4-diyl diacetate
In the enanti-omerically pure title compound, C(15)H(15)NO(6), the five-membered ring displays a twist conformation with the local axis through the N atom. The acetyl groups are perpendicular to the ring [dihedral angles 80.3 (1) and 89.3 (1)°] and project to opposite sides. The packing is governed by two weak C-H⋯O inter-actions, forming layers of mol-ecules parallel to the ab plane.
متن کاملBiphenyl-2,2′-diyl diacetate
In the title compound, C(16)H(14)O(4), a derivative of 2,2'-biphenol, the benzene rings are oriented at a dihedral angle of 58.32 (3)°.
متن کامل5-[2-(4-Acetyloxyphenyl)ethenyl]benzene-1,3-diyl diacetate
The title compound, C(20)H(18)O(6), was prepared from resveratrol {systematic name: 5-[(E)-2-(4-hy-droxy-phen-yl)ethen-yl]ben-z-ene-1,3-diol}, which can be isolated from grapes, through triacetyl-ation with using acetic anhydride in pyridine. The two benzene rings are approximately coplanar, making a dihedral angle of 6.64 (14)°, and the three acet-oxy group are located on the same side of the ...
