rac-(1R,2S,6R,7R)-4-{[(1E)-(2-Chlorophenyl)methylidene]amino}-1-isopropyl-7-methyl-4-azatricyclo[5.2.2.02,6]undec-8-ene-3,5-dione

Abstract

The title compound, C21H23ClN2O2, was synthesized from N-amino-α-terpinene maleimide and 2-chlorobenzaldehyde. There are two independent molecules in the asymmetric unit which are linked via an intermolecular C—H...O hydrogen bond. The crystal studied was found to be a partial merohedral twin, with a 0.74 (7):0.26 (7) domain ratio.
