Benzyl 2-(4-bromoanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate: first triclinic polymorph
The six-membered cyclohexene ring in the title compound, C22H22BrNOS2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.686 (4) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.025 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond
n-Undecanyl 2-(4-bromoanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate
The six-membered cyclohexene ring in the title compound, C26H38BrNOS2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.651 (3) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.051 Å). The molecular conformation is stabilized by an N—H⋯S hydrogen bond. The title compound is isomorphous with n-undecanyl 2-(4-chloroanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate

2,3,4,6-Tetra-O-acetyl-β-d-galactopyranosyl 2-(2,4-dichloroanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate
The cyclohexene ring in the title compound, C29H33Cl2NO10S2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.63 (1) Å from the plane through the other five ring atoms (r.m.s. deviation = 0.11 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond. The crystal studied was a non-merohedral twin, with a minor twin component of 29%
n-Undecanyl 2-(4-chloroanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate
The six-membered cyclohexene ring in the title compound, C26H38ClNOS2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.642 (4) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.053 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond
2-Hydroxyethyl 2-(2,4-dichloroanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate
The six-membered cyclohexene ring in the title compound, C17H19Cl2NOS2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.716 (3) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.072 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond. The hydroxy group engages in intermolecular O—H⋯O hydrogen bonding with adjacent acceptor atoms to generate a zigzag chain running along the c axis
