(Received 1 September 2010; accepted 2 September 2010; online 8 September 2010)

The title compound, C15H14ClNO2, was synthesized as part of a project to generate a combinatorial library based on the fungal natural product 2-(3-chloro-4-hy­droxy­phen­yl)acetamide. It crystallizes as non-planar discrete mol­ecules [the peripheral 3-chloro-4-hy­droxy­phenyl and benzyl groups are twisted out of the plane of the central acetamide group, with N—C—C—C and C—C—C—C torsion angles of −58.8 (3) and 65.0 (2)°, respectively] linked by inter­molecular N—H⋯O and O—H⋯O hydrogen bonds.

Comment top

The title compound (I) (Fig. 1) was synthesized during the generation of a combinatorial library based on the fungal natural product 3-chloro-4-hydroxyphenylacetamide and was shown to display moderate cytotoxicity towards the human melanoma cell line MM96L and the human prostate cell line DU145 with IC50 values of 72 and 51 µM respectively (Davis et al., 2007). Although many organohalogen natural products have been identified (Gribble, 1996), only three crystal structures on compounds incorporating the 3-chloro-4-hydroxyphenylacetamide moiety have been reported to date (Krohn et al., 1992; Davis et al., 2005; Davis & Healy, 2008).

The present compound crystallizes in the chiral space group P21 as discrete molecules with the central C1—C7—C8(-08)-N1—C9—C10 fragment approximately planar. The peripheral 3-chloro-4-hydroxyphenyl (C1—C7, O4, Cl3) and benzyl (C9—C15) groups are twisted out of the plane of the central acetamide group with N1—C9—C10—C11 and C2—C1—C7—C8 torsion angles of -58.8 (3) and 65.0 (2) °, respectively (Fig. 1). In the crystal lattice the amide (N1) and hydroxy (O4) groups form inter-molecular N—H···O and O—H···O hydrogen bonds with the carbonyl O atoms (O8) at (1 + x, y, z) and (-x - 1, y + 1/2, 1 - z), respectively (Table 1 & Fig. 2).

Experimental top

Compound (I) was prepared and analytically and spectroscopically characterized as previously reported (Davis et al., 2007; Poulsen et al., 2006). Crystals suitable for X-ray diffraction studies were obtained by recrystallization from a solution of the compound in a solvent mix of 90% methanol, 10% water, and 0.1% trifluoroacetic acid.

Refinement top

The carbon-bound H atoms were constrained as riding atoms with C—H = 0.93–0.96 Å. The amide and hydroxyl protons were located in difference Fourier maps and constrained with N—H 0.86 Å and O—H = 0.90 Å in the final refinement. Uiso(H) values were set at 1.2Ueq of the parent atom.

Special details top

Experimental. CrysAlisPro (Oxford Diffraction, 2010). Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
