8-{[(E)-3-(2-Chloro-phen-yl)acrylo-yloxy]imino}-12,13-ep-oxy-trichethec-9-en-4-yl (E)-3-(2-chloro-phen-yl)acrylate.
In the title compound, C(33)H(31)Cl(2)NO(6), 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 ep-oxy ring, making dihedral angles of 87.53 (4) and 88.67 (4)°, respectively.
