In the title molecule, C13H13ClN2OS, the heterocyclic ring adopts a flattened boat conformation, and the plane through the four coplanar atoms makes a dihedral angle of 87.92 (10)° with the benzene ring. The thione, acetyl and methyl groups have equatorial orientations with respect to the attached heterocyclic ring. The chlorophenyl group has an axial orientation. Intermolecular N—H⋯O, N—H⋯S and C—H⋯O hydrogen bonds are found in the crystal structure.
In the title molecule, C21H19ClO3, the cyclohexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Intermolecular C—H⋯O hydrogen bonds and intramolecular C—H⋯Cl contacts are found in the crystal structure; a weak C—H⋯π interaction is also present.
In the title molecule, C13H13ClN2O2, the heterocyclic ring adopts a flattened boat conformation with the plane through the four coplanar atoms making a dihedral angle of 89.16 (5)° with the benzene ring, which adopts an axial orientation. The carbonyl, acetyl and methyl groups each have an equatorial orientation. In the crystal structure, intermolecular N—H⋯O hydrogen bonds lead to a tape motif. The H atoms of the methyl group at position 6 are disordered over two positions of opposite orientation.
In the title molecule, C16H13FOS, the dihedral angle between the two benzene rings is 8.68 (6)°. The H atoms of the central enone group are trans and one H atom is involved in a close intramolecular C—H⋯O contact. The crystal structure is stabilized by weak C—H⋯π interactions.
In the title compound, C21H19BrO3, the cyclohexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 28.88 (10) and 71.94 (10)° with the bromobenzene and phenyl rings, respectively. The dihedral angle between the latter two rings is 51.49 (15)°. Intermolecular C—H⋯O hydrogen bonds are found in the crystal structure; a C—H⋯π interaction is also present.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
