4,11-Bis(4-chlorophenyl)-3,10-bis(2,6-dichlorophenyl)-1,8-dioxa-2,9-diazadispiro[4.1.4.2]trideca-2,9-dien-6-one-chloroform-methanol (1/1/0.75)

Abstract: The title compound, C32H20Cl6N2O3·CHCl3·0.75CH4O, was synthesized by the intermolecular [3 + 2]-cycloaddition of 2,6-dichlorobenzonitrile oxide and 2,5-bis(4-chlorobenzylidene)cyclopentanone. There are three five-membered rings linked by two spiro-C atoms, with approximate C2 symmetry. The cyclopentane ring has a twist conformation and the two isoxazoline rings are envelopes.
