采用Chiralcel OD H和Chiralpak AD H手性柱,研究5种新近合成的外消旋双芳基硒代甘油硫醚和 4 种芳基硒代甘油烷氧醚对映体的高效液相色谱拆分方法.对比这两种手性固定相、异丙醇和乙醇流动相调节剂、以及样品结构对硒代甘油醚色谱拆分的影响.除样品(1c)外,其他8个外消旋硒代甘油醚样品均可达到基线拆分.
The enantioseparation of 3-alkyl-isoindolin-1-ones(1—9) and 3-alkyl-3-hydroxy-isoindolin-1-ones(10—14)(R=Me,Et,n-Pr,n-Bu,n-C5H 11 ,n-C7H 15 ,i-Bu,Ph and Bn),as well as 3-n-heptyl-2-[2-hydroxy-1-phenylethyl]-isoindolin-1-one(15) by HPLC using (S)-tert-leucine and (S)-1-α-NEA as a chiral stationary phase,and 1%—6%(volume fraction) 2-propanol or ethanol in hexane as the mobile phase was studied. The effect of content of polar solvent in mobile phase on the enantioseparation was discussed. The effects of 3-substituents on retention factor and chiral recognition were studied. For the majority of racemates(1—14),a baseline separation could be obtained. For racemate(15),the elution orders are (3R,1′R)/(3S,1′S) then (3R,1′S)/(3S,1′R) with n-hexane/2-propanol(volume ratio 99∶1) as a mobile phase and the resolutions are 1.44 and 5.58,respectively.
