Rac-6-Eth-oxy-3,3a,4,9b-tetra-hydro-1,3-diphenyl-1H-chromeno[4,3-c]isoxazole-3a-carbonitrile.

ABSTRACT: The title compound, C(25)H(22)N(2)O(3), with three stereogenic centres, crystallizes in a centrosymmetric space group as a racemate. The pyran ring adopts a sofa conformation and the five-membered isoxazole ring exhibits an envelope conformation. The dihedral angle between the benzene ring and the mean plane through the near coplanar atoms of the pyran ring is 10.54 (9)°. In the crystal, no significant intermolecular interactions are observed.
