solid solution containing 8% of S-(+)-2; the latter was isolated in enantiomerically pure form by column chromatography. This simple optical resolution procedure may represent an alternative to chiral HPLC for the preparation of small quantities of pure enantiomers, and the determination of their absolute configurations.
在少量
硫类似物(±)-2存在下,使酮S -(+)- 1结晶,得到固溶体,其中含有8%的S-(+)- 2。后者通过柱色谱分离为对映体纯形式。这种简单的光学拆分方法可代表手性HPLC的替代方法,用于制备少量纯对映体,并确定其绝对构型。
