실험 절차

95.8 mg (0.27 mmol) of 2-acetyloxy-2′-vinyloxy1,1′-binaphthyl and 9.0 mg (0.014 mmol) of Co(OAc) (L3) were dissolved in 0.27 ml of a mixed solvent (2:1) of methanol and THF under the atmosphere, 25 μl (1.44 mmol) of water was added to the mixture, and the mixture was then stirred at 0° C. After 21 hours, the reaction solution was purified by silica gel column chromatography and as a result, 34% of 2-acetyloxy-2′-vinyloxy-1,1′-binaphthyl was left with an optical purity of 86% ee measured by HPLC. The reaction product O-acetylbinaphthol was obtained in a yield of 66%. Also, the kre1 value showing the selectivity of reactions at this time was 6.6.
