The enantiomeric composition and absolute configuration of α-deuteriated primary carboxylic acids may be accurately determined by 1H and 2H nuclear magnetic resonance analysis of the corresponding esters of (S)-methyl 2-hydroxy-2-phenylethanoate (2). Similar methods with (S)-2-acetoxy-2-phenylethanoic acid (3) and (–)-camphanoyl chloride (1) as chiral reagents have enabled the enantiomeric purity of
α-氘代伯羧酸的对映体组成和绝对构型可以通过对(S)-2-羟基-2-苯基甲基乙酸甲酯(2)的相应酯进行1 H和2 H核磁共振分析来准确确定。用(S)-2-乙酰氧基-2-苯基乙酸(3)和(-)-樟脑酰氯(1)作为手性试剂的类似方法使得能够测定α-氘代伯醇和伯胺的对映体纯度。这些手性试剂还可用于确定手性仲酸,醇和胺的对映体组成。
