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-HS hydrogen bond. The crystal studied was a non-merohedral twin, with a minor twin component of 29%.
