Methyl 4-hydroxy-2-propyl-2H-1,2-benzothiazine-3-carboxylate 1,1-dioxide
In the title compound, C(13)H(15)NO(5)S, the thia-zine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intra-molecular O-H⋯O hydrogen bond, forming a six-membered ring. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds, resulting in zigzag chains lying along the c axis.

In the title compound, C(14)H(15)NO(6)S, the thia-zine ring adopts a distorted half-chair conformation. The structure displays several cooperative weak inter-molecular C-H⋯O hydrogen-bonding inter-actions, giving rise to a two-dimensional sheet packing motif. The CH(2) group in the meth-oxy linker to the oxirane ring, and the CH group in that ring, exhibit twofold positional disorder. The three...

The asymmetric unit of the title compound, C(10)H(9)NO(5)S, contains two independent mol-ecules. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations, with the S atoms in each mol-ecule displaced by 0.455 (3) and 0.539 (3) Å and the N atoms displaced in the opposite direction by 0.214 (3) and 0.203 (3) Å, from the planes defined by the remaining ring atoms. The cry...

In the title compound, C(25)H(21)NO(7)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by -0.284 (3) and 0.411 (3) Å, respectively, from the plane formed by the remaining ring atoms; the puckering parameters are: Q = 0.4576 (13) Å, θ = 58.6 (2) and ϕ = 34.3 (3)°. The structure is devoid of any classical hydrogen bonds. However, intra-molecula...
