The absolute configuration of (+)-α-methylphenylglycine was proved to be S series by the chemical correlation with R (-)-isovaline. Chemical scheme employed was shown in Chart 1. Moreover, in the course of the chemical correlation, the absolute configuration of (+)-1-methyl-1-phenylpropylamine was also proved to be R series. Preliminary experiments using racemic compounds were also described.
通过与 R (-)-isovaline 的
化学关联,证明 (+)-α-methylphenylglycine 的绝对构型为 S 系列。采用的
化学方案如图 1 所示。此外,在
化学关联过程中,(+)-1-甲基-1-苯基
丙胺的绝对构型也被证明为 R 系列。此外,还介绍了使用外消旋化合物进行的初步实验。
