The title compound, C 20 H 22 ClNO 3 , was synthesized by the reaction of 3-chlorobenzaldehyde, 5,5-dimethyl-1,3-cyclohexanedione and methyl 2-aminocrotonate in an ionic liquid medium. The X-ray analysis reveals that the nitrogencontaining ring adopts a boat conformation and the cyclohexene ring has
