Preparation of(R)-2-chloro-1-(m-chlorophenyl)ethanol by Lipozyme TL IM-catalyzed second resolution

(R)-2-Chloro-1-(m-chlorophenyl)ethanol, 是为几 3-adrenergic 受体收缩筋的准备的关键 chiral 中介的(R)-3-chlorostyrene 氧化物的一位先锋被相应 racemate 的 Lipozyme TL 催化 IM 的秒决定面对乙烯基醋酸盐在 40% 产量和 99% ee 准备。

（R）-2-Chloro-l-（m-chlorophenyl）ethanol,a precursor of（R）-3-chlorostyrene oxide which is the key chiral intermediate for the preparation of severalβ3-adrenergic receptor agonists was prepared in 40%yield and 99%ee by the Lipozyme TL IM-catalyzed second resolution of the corresponding racemate in the presence of vinyl acetate.
