    2,6-Bis[(S)-4-benzyl-4,5-dihydro-1,3-oxazol-2-yl]pyridine
    (Chester : International Union of Crystallography, 2011) Möller, K.; Junge, K.; Spannenberg, A.; Beller, M.
    The commercially available title compound, C25H 23N3O2, has been known since 1993 [Nesper et al. (1993). Helv. Chim. Acta, 76, 2239-2249], but has not been structurally characterized until now. In the free ligand, the N atoms of both oxazoline rings point in opposite directions. The phenyl rings make dihedral angles of 30.56 (5) and 84.57 (3)° with the pyridine ring and 72.85 (3)° with each other.
