Dinitriles (5-7, 12, 13) react with enantiomerically pure β-amino alcohols (8-11, 17) under zinc chloride catalysis to give optically active C2-symmetric bis(oxazolines). 1,2-Bis(2-oxazolin-2-yl)benzenes 1a-e are obtained under mild reaction conditions. 1H-NMR spectroscopy indicates the formation of 1:1 complexes 23 of these compounds with ZnCl2.The energy required for a conformational interconversion of zinc dichloride complex 23e was determined by variable-temperature 1H-NMR studies.An X-ray structure analysis was performed with the substituted zinc dichloride complex 23a.
