Comment top

It is well known that most biological reactions are catalysed by enzymes under mild conditions, with high efficiency and selectivity. It is interesting to develop small molecules or complexes as catalysts to mimic some aspect of enzyme function in organic reactions, especially in the synthesis of structurally complicated compounds. Copper–amine complexes have been frequently used to mimic oxidases (Liang et al., 1999; Mahadevan et al., 2000) since many oxidases contained copper in their active sites (McGuirl & Dooley, 1999). Catalytic oxidation using dioxygen as sole oxidant was believed to be environmentally friendly since the resulting product was water (Choudary et al., 2000). Successful application of copper–amine complexes in aerobic oxidative synthesis had been reported (Marko et al., 1996; Nakajima et al., 1999; Tan et al., 2001). In our work, similar to that of Nakajima et al. (1999), the complex of CuCl2–ethanolamine (Tan et al., 2001) in n-propanol led to a domino reaction from 1,1'-bi-2-naphthol, (I), to yield the title compound, (II), a racemic multicyclic unsaturated ketone containing an n-propoxy group derived from the solvent n-propanol. The reaction could even take place at room temperature in high yield. Three conversions occurred from (I) to (II), i.e. 2'-O—C8 coupling, 2-OH oxidation and C1–OCH2CH2CH3 coupling. The racemic structure of (II) was confirmed by 1H NMR, 13C NMR, IR, FAB–MS and elemental analysis, further confirmed by this single-crystal X-ray analysis.

As shown in Fig. 1, the molecule is composed of five fused rings with the propoxy group attached to a chiral C atom. The geometries of the two molecules show no unexpected features.

Experimental top

The title compound, (II), was synthesized from 1,1'-bi-2-naphthol, (I), in n-propanol in the presence of dioxygen under the catalysis of the CuCl2–ethanolamine complex. Compound (II) was isolated as the main product, in a yield of 92%. The single-crystal used for X-ray analysis was recrystallized from acetone.

Refinement top

The structure was solved by direct methods and all non-H atoms were refined by the full-matrix least-squares method (SHELXTL97) with anisotropic displacement parameters, except for C22 and C23 which are disordered over two positions. The H atoms were placed in calculated positions and refined using a riding model.

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.
