(S)-2-[(S,E)-4-(4-Chlorophenyl)-1-nitrobut-3-en-2-yl]cyclohexanone
Abstract
The title compound, C16H18ClNO3, was obtained by the organocatalytic asymmetric Michael addition of cyclohexanone to 1-chloro-4-[(1E,3E)-4-nitrobuta-1,3-dienyl]benzene. The double bond has an E configuration. The cyclohexanone ring adopts a chair conformation. The conformation of the molecule is stabilized by a weak intramolecular C—H...O hydrogen bond.
