Abstract
In the title compound, C16H17NO4S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.070 (1) 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 89.09 (6)°. An intramolecular C—H⋯S hydrogen bond occurs. In the crystal, C—H⋯O hydrogen bonds generate R 2 2(8) rings and π–π interactions occur between fused benzene rings of the chromene system [shortest centroid–centroid distance = 3.5487 (8) Å].
