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

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 ket...
