(R)-2-Methyl-5-[(R)-2,4,4,4-tetrachlorobutan-2-yl]cyclohex-2-enone

Abstract

The title compound, C11H14Cl4O, was efficiently synthesized by atom-transfer radical addition between (R)-carvone and tetrachloromethane. In the molecule, both chiral centres are of the absolute configurationR. The cyclohex-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, molecules are linkedviaC—H...O interactions, leading to the formation of helical chains propagating along [100].
