8-Bromo-3-(4-ethylphenyl)-1-phenyl-3,3a,4,9b-tetrahydro-1H-chromeno[4,3-c]isoxazole-3a-carbonitrile

Abstract

In the title compound, C25H21BrN2O2, the fused isoxazolidine ring adopts an envelope conformation with the N atom at the flap and the mean plane of the ring makes dihedral angles of 54.37 (12) and 87.32 (13)°, respectively, with the adjacent phenyl and benzene rings. The tetrahydropyran ring has a half-chair conformation. In the crystal, molecules are linked into a double-column structure along the b-axis direction through weak C—H...O and C—H...π interactions.
