Abstract: The title compound, C₁₁H₁₄Cl₂O, was synthesized by the reaction of a dichloromethane solution of (R)-carvone and potassium tert-butanolate in the presence of a catalytic amount of benzyltriethylammonium chloride in chloroform. The cyclohexene ring adopts a half-boat conformation. The cyclopropyl ring is unsymmetrical, the shortest C-C bond being distal to the alkyl-substituted C atom. The crystal packing is stabilized only by van der Waals interactions.
