title: Crystal structure of methyl 1-allyl-4-methyl-1H-benzo[c][1,2]thia-zine-3-carboxyl-ate 2,2-dioxide.
abstract: In the title compound, C14H15NO4S, the di-hydro-thia-zine ring adopts a distorted sofa conformation with the S atom displaced from the mean plane through the N and C ring atoms by 0.767 (1) Å. The allyl substituent (C-C=C) is inclined to this mean plane by 78.5 (7)° and the acetate group [C(=O)-O-C] by 66.5 (3)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions forming chains propagating along thea-axis direction.
