A new chiral anisotropic reagent, phenylglycine methyl ester (PGME), developed for the elucidation of the absolute configuration of chiral alpha,alpha-disubstituted acetic acids, has turned out to be applicable to other substituted carboxylic acids, such as chiral alpha-hydroxy-, alpha-alkoxy-, and alpha-acyloxy-alpha, alpha-disubstituted acetic acids, as well as to chiral beta, beta-disubstituted
为了阐明手性α,α-二取代乙酸的绝对构型而开发的一种新的手性各向异性试剂苯甘氨酸甲酯(PGME)已证明可用于其他取代的羧酸,例如手性α-羟基- ,α-烷氧基-和α-酰氧基-α,α-二取代的乙酸,以及手性β,β-二取代的丙酸。由于羧基部分可从其他官能团转化而来,例如烯烃的臭氧分解和二醇的氧化裂解,因此,本发现可将PGME方法的用途扩展到各种类型有机化合物的绝对构型测定,甚至那些最初缺乏氧气功能。描述了化学反应和PGME方法结合的几个例子。
