The long-chain aliphatic-group-substituted mandelic acid 3c, which is soluble only in THF and insoluble in water and many polar/nonpolar organic solvents, has been synthesized. This unique solubility allows 3c to be easily isolated from reaction mixtures and makes it potentially useful for catalyst screening. The fluorescent sensors (R)- and (S)-1 can be used to determine the ees of various samples
合成了仅溶于THF,不溶于水和许多极性/非极性有机溶剂的长链脂族基取代的扁桃酸3c。这种独特的溶解度使3c可以轻松地从反应混合物中分离出来,并使其有可能用于催化剂筛选。荧光传感器(R)-和(S)-1可用于确定从一系列催化剂筛选实验中生成的3c的各种样品的ee。荧光测量值与常规HPLC手性色谱柱分析密切相关。这项工作表明,对有机底物的对映选择性荧光识别可以导致从根本上筛选手性催化剂的新方法。[反应:看文字]
