Abstract top

The title compound, C18H23NO3, the adamantane derivative of norcantharidin, which is itself derived from cantharidin, crystallized with three independent molecules in the asymmetric unit. In the crystal, molecules are linked by intermolecular C-H...O interactions, leading to the formation of a supramolecular two-dimensional network.

Comment top

Norcantharidine {(I) = 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic anhydride}, derived from cantharidin {(II) = 2,6-Dimethyl-4,10-dioxatricyclo-[5.2.1.02,6]decane-3,5-dione}, is a low toxicity anticancer drug (Shimi & Zaki, 1982). A number of norcantharimides have been synthesized from norcantharidin and have been shown to possess interesting anticancer activity (Hill et al., 2007; Tan, 2009). In order to study the relationship between the anticancer activity of norcantharidin and the adamantane norcantharimide derivative, the title compound (III) was synthesized and its crystal structure is reported on here.

Compound (III) crystallized with three independent molecules per asymmetric unit, Fig. 1. The bond distances and angles in the three independent molecules are very similar and close to those observed in a similar compound, the phenyl derivative of norcantharidin (Zhu & Lin, 2009).

In the crystal structure the individual molecules are linked via C-H···O interactions leading to the formation of a supramolecular network (Table 1).

Experimental top

Norcantharidin (1.0 g) and adamantine (0.9 g) were dissolved in DMF (10 mL) and the mixture was heated to reflux with stirring for 18 h. The solvent was then evaporated off and the crude product remaining was dissolved in warm acetone (10 mL) and cooled rapidly. The clear solution obtained was left undisturbed at 255 K for several days and gave finally colourless crystals of the title compound.

Refinement top

The H-atoms were included in calculated positions and treated as riding atoms: C-H = 0.97 - 0.98 Å, with Uiso(H) = 1.2Ueq(parent C-atom).

Experimental. CrysAlisPro (Oxford Diffraction, 2009) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

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