以3-氯代苯丙酮為原料合成(S)-(-)-3-氯-1-苯基-1-丙醇的一般步驟如下:在氬氣保護(hù)下,將3.36 g(40.0 mmol)甲酸鉀(HCOOK)作為氫源,2.609 mg(4.0 μmol)Cp*IrCl[(S,S)-MsDPEN]作為催化劑,與1.349 g(8.0 mmol)β-氯苯丙酮置于20 mL Schlenk管中。向反應(yīng)體系中加入2 mL水和2 mL甲苯,將所得混合物在50℃下攪拌反應(yīng)24小時(shí)。反應(yīng)完成后,用3 mL水洗滌有機(jī)相三次,隨后在減壓條件下蒸餾除去甲苯,得到光學(xué)活性的(S)-(-)-3-氯-1-苯基-1-丙醇。通過(guò)GC分析確認(rèn),產(chǎn)物的光學(xué)純度為85% ee,產(chǎn)率為94%。
