Abstract top

The two oxazolidine rings (A and B) of the title compound, C34H44N2O4, display roughly half-chair conformations, which could be described as twisted on the C-O bond. Together, the fused oxazolidine rings have a butterfly shape, with the H atoms attached to the ring junction C atoms in a cis orientation. The cyclohexane rings of both p-menthone fragments display chair conformations. The absolute configuration could not be determined from the X-ray diffraction data, but the relative configuration of the stereocentres could be deduced.

Comment top

Synthesis of various p-menthane derivatives is studied extensively, with the goal to obtain biologically active and ecofriendly corrosion inhibitor compounds (Ito et al., 2009; Kharchouf et al., 2011; 2012; Majidi et al., 2010). p-Menthan-3-one, 1 (Menthone) have become the key starting natural compound for the synthesis of a number of substances exhibiting various kinds of biological activity (Ito et al., 2009). Menthone, a monoterpene ketone, occurs in nature and is widely present in high concentration in a few Mentha species, such as Mentha specata aromentha (Clark, 1990), M. Avrvensis (Umemoko, 1998) and the essential oils of pepperimint and other mint oils (Boelens, 1993). On the other hand, isoxazolidine rings are the frame of a number of natural products and antibiotics and are extensively used in the synthesis of a great many biologically important compounds (Wagner et al., 2004). The goal of the present study was to obtain a new p-menthane derivative having two isoxazolidine moieties. This latter is of interest, because it can exhibit biological activity and has useful properties as precursor for synthesis.

The structure of the title compound is built up from two fused five membered oxazolidine rings sharing two C atoms to which p-menthone and phenyl rings are attached (Fig. 1). As observed in other diisooxazolidines (Iball et al., 1968; 1986; Aurich et al., 1989), the two oxazolidine rings display roughly half-chair conformation with the puckering parameters Q(2)= 0.366 (2) Å and φ= 350.2 (3)° for ring A (C1, C2, C3, O1, N2) and Q(2)= 0.360 (2) Å and φ(2= 347.7 (3)° for ring B (C2, C3, C4, O2, N3) (Cremer & Pople, 1975). They could be regarded as twisted on C1—O1 and C4—O2, respectively. This two fused rings have a butterfly shape with the H atoms attached to the C2—C3 edge in cis position. Both p-menthone fragments display a chair conformation with the puckering amplitudes of θ= 180.0 (2)°, φ= 74 (10)° and θ= 1.2 (2)°, φ= 314 (8)° respectively. The packing is stabilized only by van der Waals interactions.

Experimental top

2-Hydroxymethyle menthone (1) and n-diphenylnitrone (2) were prepared according to literature procedures (Brüning et al., 1973; Tanka et al., 1972).

To a mixture of 6 mmoles of 2-hydroxymethylene menthone and 6 mmoles of n-diphenylnitrone in 20 ml of ethyl acetate (Fig. 2) was added a catalytic amount of K10 (montmorillonite/FeIII). The reaction mixture was stirred for 48 h at 25°C and then filtered. The solvent was removed and the product was purified by recrystallization in ethanol (yield 67%). Single cristals were obtained by slow evaporation of an ethanol solution at room temperature.

Refinement top

In the absence of significant anomalous scattering, the absolute configuration could not be reliably determined, so any reference to the Flack parameter was removed.

All H atoms attached to C atoms were fixed geometrically and treated as riding with C—H = 1.0 Å (methine), 0.99 Å (methylene) or 0.98 Å (methyl), with Uiso(H) = 1.2Ueq(CH, CH2) or Uiso(H) = 1.5Ueq(CH3).

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.
