Approaches are described to the synthesis of a series of isotopically labelled L-α-amino acids each with an asymmetric centre at C-3, including isoleucine, allo-isoleucine, threonine and allo-threonine. The methods may be simply adapted for the selective incorporation of an isotopic label at each site of L-valine including the selective labelling of either diastereotopic methyl group with carbon-13
描述了合成一系列同位素标记的L -α-氨基酸的方法,每个氨基酸在C-3处具有不对称中心,包括异亮氨酸, 同种异亮氨酸, 苏氨酸 和 异基因-苏氨酸。所述方法可以简单地适于将同位素标记物选择性地掺入到所述细胞的每个位点。大号缬氨酸 包括对非对映异构体的选择性标记 甲基 碳13和/或氘和 贴标 的 胺 和 氮15。
