The resolution of racemic 2,3-methanopyroglutamic acid (∇Glp) was accomplished using L- and D-Leu-NH2 and both isomers were hydrolyzed to give optically active (Z)-2,3-methanoglutamic acids1) (∇ZGlu), respectively. The optical rotations of these samples were compared with ∇ZGlu obtained by hydrolysis of ∇Glp prepared by oxidation of (2S,3R)- or (2R,3S)-2,3-methanoproline1) (∇Pro), the absolute configurations
使用 L- 和 D-Leu-NH2 完成外消旋 2,3- 甲基焦谷氨酸 (∇Glp) 的拆分,并将两种异构体水解,得到旋光 (Z)-2,3- 甲基谷氨酸 1) (∇ZGlu),分别。将这些样品的旋光度与通过 (2S,3R)- 或 (2R,3S)-2,3-methanoproline1) (∇Pro) 氧化制备的∇Glp 水解获得的∇ZGlu 进行比较,其中的绝对构型之前通过 X 射线衍射确定。这些实验表明 (-)- 和 (+)-∇Glp 分别具有 (2S,3S)- 和 (2R,3R)- 构型。
