In the title compound, C(24)H(24)O(4), a derivative of the potent insecticide and miticide spiro-mesifen, one cyclo-pentane C atom is disordered over two positions with occupancies of 0.574 (12) and 0.426 (12), resulting in respective envelope and twisted conformations for the cyclo-pentane ring. The atom at the flap position is 0.620 (5) Å out of the mean(More)
In the title compound, C(28)H(31)ClO(4), the five-membered cyclo-pentyl ring displays an envelope conformation with the atom at the flap position 0.519 (3) Å out of the mean plane formed by the other four atoms. The furan ring makes dihedral angles of 72.9 (1) and 82.4 (1)°, respectively, with the trimethyl- and chloro-phenyl rings. The dihedral angle(More)
In the title compound, C(17)H(16)Cl(2)O(4), the cyclo-hexyl ring displays a chair conformation [the four C atoms are planar with a mean deviation of 0.001 (2) Å and the two C atoms at the flap positions deviate by 0.625 (2) and -0.680 (2) Å from the plane]. The furan ring is planar with a mean deviation of 0.004 (2) Å and forms a dihedral angle of 46.73(More)
