Novel chiral derivatising agents (CDAs) such as methyl itaconate–anthracene adducts (MIAs) were reported for the absolute configuration determination of chiral secondary alcohols by the 1H NMR technique. These adducts were facilely prepared through well-known reactions, and furthermore, commercially available starting materials. According to these synthetic routes, the desired MIAs were afforded in
报道了通过1 H NMR 技术测定手性仲醇绝对构型的新型手性衍生剂 (
CDA),例如
衣康酸甲酯-
蒽加合物 (MIA) 。这些加合物很容易通过众所周知的反应制备,此外,还可以通过市售的起始原料制备。根据这些合成路线,所需的 MIA 分 6 步得到,
衣康酸二甲酯的总产率为 49%。此外,所代表的 MIA 提供了显着大的
化学位移值差异 (Δ δ SR )。没有观察到来自相邻α碳的三级特征的外消旋化。
