1-Methyl-3-(2-methyl­phen­yl)-3,3a,4,9b-tetra­hydro-1H-chromeno[4,3-c][1,2]oxazole-3a-carbonitrile

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 ...

description 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 methyl­benzene rings, respectively. The mol­ecular structure is stabilized by weak C—H⋯π inter­actions.
