(R,R)-,(S,R)-1-(6-fluoro-2-chromanyl)-1,2-ethanediol 1a/1b were prepared by hydrolytic kinetic resolution (HKR) of terminal racemic epoxides using (R,R)-SalenCo(OAc) as a catalyst. Their configurations were established by comparison with two authentic samples by HPLC.
(R,R)-,(S,R)-1-(6-fluoro-2-chromanyl)-1,2-乙二醇 1a/1b 是通过末端外消旋环氧化物的水解动力学拆分 (HKR) 制备的,使用 (R, R)-SalenCo(OAc) 作为催化剂。它们的配置是通过 HPLC 与两个真实样品进行比较确定的。
