(E)-3-(4-Cyclohexyl-3-fluorobenzylidene)chroman-4-one
The title compound, C(22)H(21)FO(2), exhibits substitutional disorder of the F atom and a H atom in the asymmetric unit with different occupancies, the refined F:H ratio being 0.80 (2):0.20 (2). The dihedral angle between the fluorinated benzene ring and the benzene ring of the chromanone system is 37.30°. There are two relatively high residual electron-density peaks associated with the disorder.
متن کامل(S)-3-[(S,E)-4-(4-Chlorophenyl)-1-nitrobut-3-en-2-yl]thian-4-one
The title compound, C(15)H(16)ClNO(3)S, was obtained by the organocatalytic asymmetric Michael addition of thian-4-one to 1-chloro-4-[(1E,3E)-4-nitro-buta-1,3-dien-yl]benzene. The double bond has an E configuration and the thian-4-one six-membered ring adopts a chair conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

The title compound, C(18)H(17)NO(4), was isolated from an ethanol extract of Ophiopogon japonicus. The dihedral angle between the 4-hydroxy-3-methoxyphenyl ring and the pyrrolidine ring is 17.4 (1)°. The 4-hydroxyphenyl ring makes a dihedral angle of 69.74 (6)° with the least-squares plane through the 4-hydroxy-3-methoxyphenyl ring and the pyrrolidine ring. The conformation of the pyrrolidine f...

In the title compound, C(11)H(12)O(2), the dihedral angle between the benzene ring and the but-3-en-2-one group is 4.04 (5)°. The crystal packing features chains, parallel to [-101], composed of dimers connected by weak C-H⋯O inter-actions..
متن کامل3-[(E)-4-Methoxybenzylidene]-1-methylpiperidin-4-one
The piperidone ring of the title compound, C(14)H(17)NO(2), adopts a half-chair conformation. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions, which generate a C(8) chain running along the b axis.
