title: (S)-3-[(S,E)-4-(4-Chloro-phen-yl)-1-nitro-but-3-en-2-yl]thian-4-one.
abstract: 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.
