Methyl 1-allyl-4-hydroxy-2,2-dioxo-1H-2λ⁶,1-benzothiazine-3-carboxylate

S. V. Shishkina, I. V. Ukrainets and L. A. Petrushova

There are two independent molecules in the asymmetric unit of the title compound, C₁₃H₁₃NO₅S, in both of which the ester substituent is nearly coplanar [C—C—C—O torsion angles = 2.7 (7) and −0.8 (7)°] with the planar fragment of the bicycle due to the formation of a strong O—H

O intramolecular hydrogen bond. The vinyl group at the ring N atom is approximately orthogonal to the heterocyclic mean plane [C—N—C—C torsion angles = 103.1 (6) and 98.2 (5)°]. The refinement was performed on a two-component, non-merohedrally twinned crystal [population ratio = 0.483 (3):0.517 (3).

Comment top

Oxicams are in integral part of the range of modern non-steroidal anti-inflammatory drugs (Kleemann et al., 2008). We have carried out the synthesis and studied the peculiarities of the spatial structure of methyl 4-hydroxy-1-methyl-2,2-dioxo-1H-2λ⁶,1-benzothiazine-3-carboxylate (I) being of interest as the initial product for obtaining 4-hydroxy-2,2-dioxo-1H- 2λ⁶,1-benzothiazine-3-carboxamides. By now these compounds remain absolutely unstudied though they are isomers of oxicams and differ from them only by the reverse mutual arrangement of nitrogen and sulfur atoms in the thiazine cycle. Two molecules (IA and IB) are observed in asymmetric part of crystal unit cell. The dihydrothiazine heterocycle adopts an intermediate between twist-boat and sofa conformation (the puckering parameters [1] are: S=0.64, Θ=55.8°, Ψ=22.9° for IA and S=0.61, Θ=50.2°, Ψ=21.1° for IB). Deviations of the S1 and C8 atoms from the mean plane of the remaining atoms of this ring are 0.91 Å and 0.29 Å, respectivey, in IA and -0.84 Å and -0.23 Å, in IB. The formation of the strong O1—H···O2 hydrogen bond (Table 1) results in coplanarity of the ester substituent to the C7—C8 endocyclic double bond (the C7—C8—C9—O2 torsion angle is 2.7 (7)° in IA and -0.8 (7)° in IB). The vinyl fragment is orthogonal to the hetetocyclic plane and is coplanar to the N1—C11 bond (the C1—N1—C11—C12 and N1—C11—C12—C13 torsion angles are 103.1 (6)° IA 98.2 (5)° IB and 9.3 (9)° IA 8.5 (9)%A IB, respectively). The repulsion between allyl substituent and atoms of the bicyclic fragment [the H2···C11 distance is 2.76Å IA 2.70Å IB, H11a···C2 2.76Å IA 2.71° IB, H11b···O5 2.41Å IA 2.38Å IB as compared to the van der Waals radii sum 2.87 Å for H···C contact and 2.46 Å for H···O (Zefirov, 1997)] results in elongation of the C1—N1 bond up to 1.416 (6) Å in IA and 1.414 (6) Å in IB while its mean value is 1.371 Å (Bürgi & Dunitz, 1994).

Experimental top

Triethylamine (1.54 ml, 11 mmol) was added to the solution of methyl N-allylanthranilate (1.91 g, 10 mmol) in CH₂Cl₂ (20 ml). Chlorosulfonyl acetic acid ethyl ester (2.05 g, 11 mol) was then added dropwise with cooling and stirring and left at the room temperature for 5 h. The reaction mixture was diluted with a cold water and vigorously stirred. The organic layer was separated, dried over CaCl₂, and the solvent was distilled off (finally under reduced pressure). The residue was treated with the solution of sodium methylate (prepared from metallic sodium (0.69 g, 30 mmol) and absolute MeOH (15 ml)), taken fo reflux, and then left for 10–12 h at the room temperature. The reaction mixture was diluted with cold water and acidified with 1 N HCl to pH 3. The precipitate was filtered, washed with water, and dried. Yield 2.39 g (81%). M.p. 114–116%A C (MeOH).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
