In the title compound, C18H27Cl2NO, the cyclohexene ring has an envelope conformation, with the C atom at the 9a position as the flap. The cycloheptane ring, to which it is fused, has a boat conformation. The dihedral angle between their mean planes is 60.7 (2)°. The 1,1-dichloro-cyclopropane ring is inclined to these two ring mean planes by 88.5 (3) and 28.3 (3)°, respectively. In the crystal, molecules are linked by N—H...O hydrogen bonds, forming 61 helices along the c-axis direction. The absolute configuration of the molecule in the crystal could be fully confirmed from anomalous dispersion effects [Flack parameter = 0.020 (15)]. |
