Abstract

The asymmetric unit of the title compound, C₁₄H₂₄N₂O₅S, contains two independent molecules (A and B). In each molecule, the isothiazolidin-3-one ring adopts an envelope conformation with the methylene C atom as the flap. In the crystal, the A molecules are linked to one another by N—H⋯O hydrogen bonds, forming columns along [010]. The B molecules are also linked to one another by N—H⋯O hydrogen bonds, forming columns along the same direction, i.e. [010]. Within the individual columns, there are also C—H⋯S and C—H⋯O hydrogen bonds present. The columns of A and B molecules are linked by C—H⋯O hydrogen bonds, forming sheets parallel to (10-1). The absolute structure was determined by resonant scattering [Flack parameter = 0.00 (3)].

Chemical context

X-ray crystallographic analyses of the enzyme PTP1B have revealed an unprecedented post-translational modification that may be important in redox regulation of protein function (Zhou et al., 2011 ▸; Salmeen et al., 2003 ▸; van Montfort et al., 2003 ▸; Tanner et al., 2011 ▸; Sivaramakrishnan et al., 2010 ▸). Specifically, oxidation converts the catalytic cysteine in this enzyme to an isothiazolidin-3-one heterocycle that is commonly referred to as a sulfenyl amide residue. As part of early efforts in the area of cephalosporin synthesis, a dipeptide containing a protein sulfenyl amide residue was synthesized (Morin et al., 1973 ▸). However, to the best of our knowledge, there are no examples of low molecular weight sulfenyl amides that have been characterized crystallographically, although structures of related 1,2-benzisothiazol-3(2H)-ones have been reported (Kim et al., 1996 ▸; Ranganathan et al., 2002 ▸; Wang et al., 2011 ▸). Herein we describe the synthesis and crystal structure of the title compound, a low molecular weight mimic of oxidized PTP1B. graphic file with name e-71-00741-scheme1.jpg

Structural commentary

The molecular structures of the two independent molecules (A and B) of the title compound are shown in Fig. 1 ▸. The two molecules differ only in the orientation of the isopropyl group (Fig. 1 ▸). The bond lengths and angles are very similar to those seen in the crystal structures of the oxidized enzyme PTP1B (see: pdb codes 1oem, 1oes, 3sme). In both molecules, the isothiozolidin-3-one ring adopts an envelope conformation with the methylene C atom (C1A in molecule A and C1B in molecule B) as the flap, similar to the conformation of oxidized PTP1B (pdb code: 1oem). In previously reported chemical models (1,2-benzisothiazole compounds) of PTP1B, the five-membered ring is planar (Kim et al., 1996 ▸; Ranganathan et al., 2002 ▸; Wang et al., 2011 ▸; Sivaramakrishnan et al., 2005 ▸). The S—N bond lengths in the title compound [S1A—N1A = 1.740 (2) Å and S1B—N1B = 1.733 (2) Å], are similar to the same bond distance of ca 1.71 Å in oxidized PTP1B (pdb code: 1oem).

Supramolecular features

In the crystal, N—H⋯O hydrogen-bonding interactions give infinite, separate columns of A and B molecules along the b-axis (Table 1 ▸ and Fig. 2 ▸). Within the columns there are C—H⋯S and C—H⋯O hydrogen bonds present (Table 1 ▸). The columns of A and B molecules are linked by C—H⋯O hydrogen bonds, forming sheets parallel to (10 Inline graphic ); see Fig. 2 ▸.

Database survey

A search in the Cambridge Structural Database (Version 5.36; Groom & Allen, 2014 ▸) for the substructure 1,2-benzisothiazole-3-one resulted in over twenty hits, which include three structures similar to the title compound: methyl 2-hydroxy-2-(3-oxobenzo[d]isothiazol-2(3H)-yl)propanoate (Ranganathan et al., 2002 ▸), 2-(3-oxobenzo[d]isothiazol-2(3H)-yl)acetic acid (Wang et al., 2011 ▸) and 2-phenethylbenzo[d]isothiazol-3(2H)-one (Kim et al., 1996 ▸). In all three compounds, the five-membered isothizolinone ring is planar. However, the S—N bond lengths are similar to that in the title compound; see Structural commentary.

Synthesis and crystallization

The title compound was prepared by a modification of a previously published procedure (Shiau et al., 2006 ▸). Pyridine (20 eq) was added to a solution of l-valine ester of N,N-di-tert-butyloxycarbonyl-l-cystine (1.0 g, 1.5 mmol) in 50 mL of anhydrous CH₂Cl₂. The solution was cooled in a liquid nitrogen bath, under an N₂ atmosphere, and stirred for 15 min. Bromine (135 µL, 2.6 mmol) in dry CH₂Cl₂ was added dropwise over a period of 30 min. The solution was allowed to warm to 273 K over 1 h, and then CH₂Cl₂ was evaporated in vacuo using a rotatory evaporator to afford the crude material. Flash chromatography (50% EtOAc/hexanes) of the crude material gave the title compound as a white solid (360 mg, 72% yield). Crystals suitable for X-ray diffraction analysis were obtained by slow evaporation of a solution of title compound in DMF.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The H atoms were included in calculated positions and treated as riding atoms: N—H = 0.88 Å, C—H = 0.98–1.00 Å with U _iso(H) = 1.5U _eq(C) for methyl H atoms and 1.2U _eq(N,C) for other H atoms.

Special details

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.
