8-{[(E)-3-(2-Chlorophenyl)acryloyloxy]imino}-12,13-epoxytrichethec-9-en-4-yl (E)-3-(2-chlorophenyl)acrylate

In the title compound, C33H31Cl2NO6, the five-membered ring displays an envelope conformation, whereas the two six-membered rings both exhibit a chair conformation. As for the seven-membered ring, the dihedral angle between the mean planes formed by the four C atoms of the envelope unit and the three C and one O atoms of the six-membered chair is 69.08 (4)°, and these two mean planes are nearly perpendicular to the epoxy ring, making dihedral angles of 87.53 (4) and 88.67 (4)°, respectively.
