(5,7-Dimethyl-2-oxo-2H-chromen-4-yl)methyl pyrrolidine-1-carbodithio-ate
Abstract:
In the title compound, C(17)H(19)NO(2)S(2), the 2H-chromene ring system is almost planar, with a maximum deviation of 0.044 (2) Å, and the pyrrolidine ring adopts an envelope conformation. The dihedral angle between the 2H-chromene system and the planar part of the pyrrolidine ring is 83.65 (8)°. A weak intra-molecular C-H⋯S hydrogen bond occurs. The crystal structure features C-H⋯O hydrogen bonds and π-π inter-actions, with a centroid-centroid distance of 3.5728 (16) Å.
