1-{3-[(4-Oxopiperidin-1-yl)carbonyl]benzoyl}piperidin-4-one
Two independent mol-ecules comprise the asymmetric unit in the title compound, C(18)H(20)N(2)O(4). One of the mol-ecules exhibits disorder in one of its 4-piperidone rings, which is disposed over two orientations [site occupancy of the major component = 0.651 (5)]. The first independent mol-ecule and the minor component of the second disordered mol-ecule are virtually superimposable. The centra...
متن کامل2,2,6,6-Tetramethyl-4-oxopiperidin-1-ium 4-chloro-3-nitrobenzoate
The title salt, C(9)H(18)NO(+)·C(7)H(3)ClNO(4) (-), was obtained as an unexpected product of the reaction of 4-chloro-3-nitro-benzoyl isothio-cyanate with pyrrolidine. The six-membered ring of the 4-oxopiperidinium cation adopts a chair conformation. In the crystal structure, two cations and three anions are linked together by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds and arranged diagonal...

In the structure of the title compound, C(27)H(39)N(3)O(3), each of the (4-oxopiperidin-1-yl)methyl residues adopts a flattened chair conformation (with the N and carbonyl groups being oriented to either side of the central C(4) plane) and they occupy positions approximately orthogonal to the central benzene ring [C(benzene)-C-C(methyl-ene)-N torsion angles 103.4 (2), -104.4 (3) and 71.9 (3)°];...

The asymmetric C atom in the title compound, C(21)H(17)BrClNO, is in a slightly distorted tetra-hedral environment and the NH unit adopts a gauche orientation with respect to the CO group. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers.
متن کامل1-(4-Methoxyphenyl)-4-(4-methylphenyl)-3-phenoxyazetidin-2-one
The central β-lactam ring of the title compound, C(23)H(21)NO(3), is almost planar (r.m.s. deviation = 0.032Å). The meth-oxy-benzene ring is almost coplanar with the β-lactam ring [dihedral angle = 1.87 (11)°], whereas the tolyl ring is almost normal to it [75.73 (12)°]. The dihedral angle between the β-lactam ring and the O-bonded phenyl ring is 51.95 (12)°. An intra-molecular C-H⋯O inter-acti...
