The absolute configuration of (+)-α-methylaspartic acid has been established to be S-configuration by the chemical correlation with (+)-isovaline, which was already correlated to D-(-)-quinic acid. The Chemical scheme employed was shown in Chart 1. Preliminary examinations using racemic compounds were also reported.
已通过与(+)-异缬氨酸的化学关联确定(+)-α-甲基天冬氨酸的绝对构型为S构型。(+)-异缬氨酸已与D-(-)-奎尼酸关联。采用的化学方案见图1。还报道了使用外消旋化合物的初步检查。
