RESUMO
In the title compound, C(16)H(17)NO(4)S(2), the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.070â (1)â Å, and the morpholine ring adopts a chair conformation; the bond-angle sum for its N atom is 357.9°. The dihedral angle between the the 2H-chromene ring and the best plane through the morpholine ring is 89.09â (6)°. An intra-molecular C-Hâ¯S hydrogen bond occurs. In the crystal, C-Hâ¯O hydrogen bonds generate R(2) (2)(8) rings and π-π inter-actions occur between fused benzene rings of the chromene system [shortest centroid-centroid distance = 3.5487â (8)â Å].
