cis‐dihydrodiol, cyclohex‐2‐en‐1‐one cis‐diol, heteroarene cis/trans‐2,3‐diol, and catechol metabolites in estimating their ee values, and 2) new chiral phenylboronic acids, 2‐[1‐methoxy‐2,2‐dimethylpropyl]phenyl boronic acid (MDPBA) and 2‐[1‐methoxy‐1‐phenylmethyl]phenyl boronic acid (MPPBA) and their advantages over MEPBA, as reagents for stereochemical analysis of arene and alkene cis‐diol metabolites, are presented
的用于确定对映体过量(方法相对优点EE)值和手性芳烃绝对构型和烯烃的顺式-1,2-二醇的代谢物,包括硼酸酯的形成,使用外消旋或对映纯的(+)和( - ) - 2-讨论了(1-甲氧基乙基)苯基硼酸(MEPBA)。的进一步的应用:1)衍生MEPBA手性的单-和多环芳烃的硼酸盐顺式-dihydrodiol,环己-2-烯-1-酮的顺式-二醇,杂芳烃顺/反式-2,3-二醇,和儿茶酚代谢物在估计他们的ee值; 2)新的手性苯基硼酸,2- [1- [1-甲氧基-2,2-二甲基丙基]苯基硼酸(MDPBA)和2- [1-甲氧基-1-苯基甲基]苯基硼酸(MPPBA)及其优势介绍了在MEPBA上作为芳烃和烯烃顺式-二醇代谢物的立体化学分析试剂。
