DIME-6-TBDS-beta-CD column, a separation of the Z- and E-isomers of methylidenementhol was accomplished; no separation was achieved with the other columns. The stereoisomers of methylidenementhol and the corresponding tert-butyldimethylsilyl (TBS) ether were separated on both the beta-CD and the heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TME-beta-CD) columns by high-performance liquid chromatography (HPLC)
在几个取代的β-环糊精(CD)色谱柱上进行了薄荷醇衍生物(合成生理活性天然产物的重要中间体)的立体异构体的气相色谱分离,其中包括全-O-甲基-β-环糊精(PME-β- CD),七(2,3-二-O-乙酰基-6-叔丁基二甲基甲硅烷基)-β-CD(DIAC-6-TBDS-β-CD)和七(2,3-二-O-甲基- 6-叔丁基二甲基甲硅烷基)-β-CD(DIME-6-TBDS-β-CD)作为手性固定相(CSP)。用DIME-6-TBDS-β-CD色谱柱可分离亚甲基薄荷醇的Z-异构体和E-异构体。其他色谱柱未实现分离。亚甲基薄荷醇的立体异构体和相应的叔丁基二甲基甲硅烷基(TBS)醚在β-CD和庚烷上均已分离(2,3,6-三-O-甲基)-β-环糊精(TME-β-CD)色谱柱通过高效液相色谱(HPLC),流动相包括乙腈和H(2)O。对于甲基亚甲基薄荷醇的Z-和E-异构体的分离,TME-β-CD色谱柱更为出色
