Propan-2-yl 2-(1,1,3-trioxo-2,3-dihydro-1λ6,2-benzothiazol-2-yl)acetate

Abstract

In the title molecule, C12H13NO5S, the benzisothiazole ring system is essentially planar (r.m.s. deviation = 0.0169 Å) as is the –C—C(=O)—O—C– sequence of atoms in the vicinity of the acetate group (r.m.s. deviation = 0.0044 Å). The mean plane of these atoms forms a dihedral angle of 88.41 (7)° with the benzisothiazole ring system. In the crystal, weak C—H...O hydrogen bonds involving methylene and methyne H atoms form R43(20) graph-set motifs.
