1-Benzyl-2,5-dioxopyrrolidine-3,4-diyl diacetate
The pyrrolidine-2,5-dione ring in the title compound, C(15)H(15)NO(6), is in a twisted conformation with the acetyl C atoms projecting to opposite sides of the ring. The acetyl groups lie to opposite sides of the five-membered ring. The benzene ring is roughly perpendicular to the heterocyclic ring, forming a dihedral angle of 76.57 (14)° with it. In the crystal, mol-ecules are connected throug...
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 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 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 کاملDi-tert-butyl 2,2′-[(biphenyl-4,4′-diyl)dioxy]diacetate
The complete molecule of the title compound, C(24)H(30)O(6), is generated by a crystallographic inversion centre. In the unique part of the mol-ecule, the four-atom -O-CH(2)-C(= O)-O- chain between the benzene ring and the tert-butyl group assumes a zigzag conformation [O-C-C-O torsion angle = -162.3 (1)°].
