反応手順

To a solution of 2.91 g (6.99 mmol) of (S)-α-cyano-3-phenoxybenzyl (R)-N-1-(1-naphthyl)ethylcarbamate in 30 ml of dry benzene under a nitrogen atmosphere is added 1.07 ml (0.78 g, 7.7 mmol) of triethylamine followed immediately by 0.75 ml (1.0 g, 7.4 mmol) of trichlorosilane. The reaction is heated at 50° for 3 hours and is then worked up and purified following the procedure of Example 4. The more polar band on the tlc plate is removed and extracted with trichloromethane to yield (S)-α-cyano-3-phenoxybenzyl alcohol, specific rotation [α]D25 =-14.6° (c=11 mg/ml in acetone).
