(2RS,5′RS)-3′,4′-Bis(4-chlorophenyl)-3,4-dihydrospiro[acridine-2,5′(4′H)-[1,2]oxazol]-1(2H)-one

Abstract

The title compound, C27H18Cl2N2O2, represents a racemic mixture of the corresponding R,R and S,S diastereomers. The isoxazoline ring adopts an envelope conformation with the spiro C atom deviating by 0.093 (2) Å from the rest of the ring. The six-membered keto-substituted carbocycle has a sofa conformation with the methyl­ene C atom adjacent to the spiro center deviating by 0.289 (2) Å from the mean plane of the remaining atoms. In the crystal, mol­ecules are linked via C—H⋯Cl inter­actions and C—Cl⋯O halogen bonds [2.958 (2) Å, 171.39 (7)°], which generate bifurcated R 2 1(6) ring motifs resulting in C 2 1[R 2 1(6)] chains running parallel to [010].
