3-Hydroxy-1-methyl-2-[4-(piperidin-1-yl)phenyl]quinolin-4(1H)-one
There are two structurally similar but crystallographically independent mol-ecules (A and B) in the asymmetric unit of the title compound, C(21)H(22)N(2)O(2), which are linked via two O-H⋯O hydrogen bonds. An intramolecular O-H⋯O hydrogen bond also occurs in each molecule. In the crystal, the A and B mol-ecules are further linked through C-H⋯O inter-actions. The benzene ring is twisted at an an...
متن کامل1-Methyl-3,3-bis[(4-methylphenyl)sulfanyl]piperidin-2-one
The piperidone ring in the title compound, C(20)H(23)NOS(2), has a half-chair distorted to a twisted-boat conformation [Q(T) = 0.5200 (17) Å]. One of the S-bound benzene rings is almost perpendicular to the least-squares plane through the piperidone ring, whereas the other is not [dihedral angles = 75.28 (5) and 46.41 (5) Å, respectively]. In the crystal, the presence of C-H⋯O and C-H⋯π inter-a...
متن کامل1-Methyl-3,5-bis[(E)-(3-methyl-2-thienyl)methylene]piperidin-4-one monohydrate
In the title mol-ecule, C(18)H(19)NOS(2)·H(2)O, the piperidine ring adopts an envelope conformation with the methyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio-phene rings is 6.04 (14)°. The water mol-ecule forms two donor inter-actions, one with the carbonyl O atom and the other to the hetero N atom. T...
متن کامل3-Hydroxy-1-(4-methoxybenzyl)piperidin-2-one
The title compound, C13H17NO3, adopts a conformation in which the aromatic ring and the mean plane of the piperidine ring are almost perpendicular to each other [dihedral angle = 79.25 (6)°]. The presence of the carbonyl group alters the conformation of the piperidine ring from a chair to a twisted half-chair conformation. In the crystal, pairs of strong O-H⋯O hydrogen bonds link the mol-ecules...
متن کامل(E)-3-(4-Methoxyphenyl)-1-[4-(piperidin-1-yl)phenyl]prop-2-en-1-one
The piperidine ring in the title compound, C(21)H(23)NO(2), is in a slightly distorted chair conformation. The dihedral angle between the two benzene rings is 5.6 (4)°. The dihedral angles between the propenone unit and the benzene and meth-oxy-substituted benzene rings are 5.6 (7) and 10.7 (8)°, respectively. Weak inter-molecular C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions contribute to ...
