1-Methyl-3-(2-methyl-phen-yl)-3,3a,4,9b-tetra-hydro-1H-chromeno[4,3-c][1,2]oxazole-3a-carbonitrile.


ABSTRACT: In the title compound, C(19)H(18)N(2)O(2), the five-membered isoxazole ring adopts an envelope conformation and the deviation of the N atom from the mean plane of the isoxazole ring is -0.3256 (11) Å. The pyran ring adopts a half-chair conformation. The isoxazole ring forms dihedral angles of 44.07 (7) and 84.23 (7)° with the pyran and methyl-benzene rings, respectively. The mol-ecular structure is stabilized by weak C-H⋯π inter-actions.
