Methyl 2-(2,3,5-trimethyl-1,1-dioxo-2H-1λ6,2,6-thiadiazin-4-yl)benzoate
There are two mol-ecules, A and B, in the asymmetric unit of the title compound, C14H16N2O4S, which is the first example reported in this family of compounds in which the Nsp(3) atom of the thia-diazine ring is methyl-ated. The thia-diazine rings adopt shallow envelope conformations, with the S atoms displaced by 0.319 (12) and 0.182 (12) Å from the mean planes of the other ring atoms in mol-ec...

The title compound, C(22)H(18)O(7), also known as laurentiquinone B, is a new anthraquinone which was isolated from Vismia laurentii, a Cameroonian medicinal plant. The asymmetric unit contains two independent mol-ecules. Each of them contains four fused rings, three of which are coplanar and typical of anthracene, while the heterocyclic rings adopt envelope conformations. Intra-molecular O-H⋯O...

In the title compound, C(18)H(17)NO(5)S, the thia-zine ring adopts a half-chair conformation and the dihedral angle between the aromatic rings is 79.41 (6)°. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions resulting in infinite sheets along the b and c axes.

In the title compound, C(14)H(17)NO(5)S, the thia-zine ring adopts a half-chair conformation. The mol-ecule exhibits an intra-molecular O-H⋯O hydrogen bond, which forms a six-membered S(6) ring motif. The planes of the benzene and thia-zine rings are inclined at a dihedral angle of 15.30 (12)°.
متن کاملN-Benzyl-4-hydroxy-2-methyl-1,1-dioxo-2H-1λ6,2-benzothiazine-3-carboxamide
In the title mol-ecule, C(17)H(16)N(2)O(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.546 (4) and 0.281 (4) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond. The two aromatic rings are inclined to one another by 4...
