Salicylaldehyde (0.24 ml, 2.3 mmol) and 9-amino-(9-deoxy)-epiquinine (0.513 g, 1.588 mmol) in toluene (40 ml) was heated to reflux. After that, two scoops of Al2O3 (about 1.5 g, dried at 110 °C for two hours before use) were added to the solution. And then added one more scoop each hour. After four hours, the temperature was slowly cooling down to room temperature. Then the mixture was filtrated and the residue was washed with Et2O. The combined organic layers were removed under reduced pressure. The residue was purified by flash
on silica gel (CH2Cl2/methanol/Et3N 30/1/1) to afford Schiff base compound 1 b (570 mg, 84% yield) as a yellow solid. HRMS (ESI, M+H) calcd for C27H30N3O2 428.2338, found 428.2333.All H atoms were placed in their calculated positions and then refined using the riding model approximation, with C—H lengths of 0.93Å (CH), 0.97Å (CH2), 0.96Å (CH3), and Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(C27).

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. |

In recent years, considerable attention has been focused on the Schiff-base ligands, e.g. as organocatalysts or ligands of metal complexes in asymmetric reactions; as biological active compounds owing to their anti-tumour abilities (Yin et al., 2004). We report here the crystal structure of the title Schiff-base compound (Fig. 1).
The molecule of the compound adopts an E configuration with respect to the C═N bond. The dihedral angle between the quinoline ring and the part of spirane C8C18C24 is 63.06°. The dihedral angle between benzene ring and quinoline ring is 65.20°. And it is 54.46° between benzene ring and the spirane part C8C18C24. All the bond lengths are within normal values (Jones, 1986; Hooft et al., 2008), and are comparable with those in the similar Cinchona alkaloid-derived Schiff base compounds as cited above (Zhu, 2011; Xie et al., 2010). The molecular conformation is stabilized by O—H···N interactions (Table 1).
