【 摘 要 】

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.
