β-Methylnorleucine and β-methylleucine were synthesized, separated into diastereomers and optically resolved. The configurational assignments of these isomers and the determinations of the optically active isomers were achieved by means of NMR spectroscopy and the enzymatic method respectively.
β-甲基正亮
氨酸和β-甲基亮
氨酸被合成、分离成差向异构体并进行光学解析。这些异构体的构型分配以及光学活性异构体的确定分别通过核磁共振波谱学和酶学方法实现。
