(Received 26 February 2008; accepted 6 March 2008; online 4 April 2008)

The title compound, C₁₈H₃₃NO₃, was prepared according to a highly diastereoselective hydrogenation procedure from 3,5,7-triallyl-1-azaadamantane-4,6,10-trione. The crystal structure of the title compound contains two crystallographically independent molecules (Z′ = 2), which are linked by intermolecular hydrogen bonding into chains. In contrast to the azaadamantanones, the azaadamantanetriol core of the title compound does not show any particular C—C bond elongation.

Comment top

Recently, an increasing number of molecular receptors based on a polyfunctionalized rigid platform have been reported (Guarise et al., 2006; Haberhauer et al., 2005 ; Li et al., 2005). Among them, adamantane and aza-adamantane scaffolds offer the guarantee of a well-defined environment as a result of axial or equatorial substituent orientation. The title compound shows a perfectly constraint face with three hydroxyl groups in axial positions that could potentially be used, after introduction of suitable ligands, as oriented binding sites for a wide range of applications.

The asymmetric unit of the title compound consists of two independent molecules(A and B) per unit-cell (Z'=2) (Steiner, 2000). This feature arises from the different orientation of one of the propyl group (C11-C12-C13 and C29-C30-C31). Contrary to the case of aza-adamantanone systems which show several C-C bond elongations (Lampkins et al., 2008), all angles and distances within the two molecules agree well with the expected values from the literature (Allen et al., 2006). Each independant molecule of the title compound displays two intra-molecular O-H···O hydrogen bonds and one O-H···N inter-molecular. The later leads to the formation of infinite one-dimensional chains along [2 0 1]. The chains are composed of alternated molecules A and B.

Experimental top

The title compound was prepared according to a hydrogenation procedure adapted from Risch (1985). A 100-ml reactor vessel was charged with 80 mg of 3,5,7-triallyl-1-aza-adamantane-4,6,10-trione (0.267 mmol) (Li et al., 2005), 88 mg of platinum oxide (0.388 mmol) and 20 ml of a 1:1 THF/0.1 N HCl mixture. The reaction mixture was hydrogenated (10 bar H₂) for 50 h at room temperature. After filtration over Celite, the aqueous solution was concentrated under reduced pressure (200 mbar) basified with potassium carbonate and extracted with four 80-ml portions of ethyl acetate. The combined organic phases were then dried over Na₂SO₄ and concentrated in vacuo. Flash chromatography purification (petroleum ether/ethyl acetate 1:1 then neat ethyl acetate) afforded the title compound as a cristalline white powder (54 mg, 65%). X-ray quality single crystals were obtained by slow evaporation from a cyclohexane/ethyl acetate solution.
