Abstract

In the title compound, C14H15NO4S, the dihydrothiazine 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, molecules are linked by C - H⋯π interactions forming chains propagating along the a-axis direction.
