title: (S)-2-[(S,E)-4-(4-Chloro-phen-yl)-1-nitro-but-3-en-2-yl]cyclo-hexa-none.
abstract: The title compound, C(16)H(18)ClNO(3), was obtained by the organocatalytic asymmetric Michael addition of cyclo-hexa-none to 1-chloro-4-[(1E,3E)-4-nitro-buta-1,3-dien-yl]benzene. The double bond has an E configuration. The cyclo-hexa-none ring adopts a chair conformation. The conformation of the mol-ecule is stabilized by a weak intra-molecular C-H⋯O hydrogen bond.
