(R)-2-Methyl-5-[(R)-2,4,4,4-tetra-chloro-butan-2-yl]cyclo-hex-2-enone.

ABSTRACT: The title compound, C(11)H(14)Cl(4)O, was efficiently synthesized by atom-transfer radical addition between (R)-carvone and tetra-chloro-methane. In the mol-ecule, both chiral centres are of the absolute configuration R. The cyclo-hex-2-enone ring has an envelope conformation with the chiral C atom displaced by 0.633?(2)?Å from the mean plane through the other five C atoms [maximum deviation = 0.036?(2)?Å]. In the crystal, mol-ecules are linked via C-H?O inter-actions, leading to the formation of helical chains propagating along [100].
