Crystal structure of methyl 3-(3-fluoro-phen-yl)-1-methyl-1,3a,4,9b-tetra-hydro-3H-thio-chromeno[4,3-c]isoxazole-3a-carboxyl-ate.


ABSTRACT: In the title compound, C19H18FNO3S, the five-membered oxazolidine ring adopts an envelope conformation with the methine C atom of the fused bond as the flap. Its mean plane is oriented at a dihedral angle of 50.38?(1)° with respect to the fluoro-phenyl ring. The six-membered thio-pyran ring has a half-chair conformation and its mean plane is almost coplanar with the fused benzene ring, making a dihedral angle of 4.94?(10)°. The two aromatic rings are inclined to one another by 85.96?(11)°, and the mean planes of the oxazolidine and thio-pyran rings are inclined to one another by 57.64?(12)°. In the crystal, mol-ecules are linked by C-H?? inter-actions, forming a three-dimensional structure.
