sativus, β-N-oxalyl-α,β-diaminopropionic acid, was thermally isomerized to an equilibrium mixture (60/40) containing the non-toxic α-N-oxalyl-α,β-diaminopropionic acid. The same equilibrium mixture was established by starting with the α-isomer but required longer time. α- and γ-N-Oxalyl-α,γ-diaminobutyric acids also underwent thermally induced isomerization with α-γ, or γ-α migration of the oxalyl group
摘要 豆科植物 Lathyrus sativus 的神经毒性成分 β-N-草酰-α,β-二氨基丙酸被热异构化为含有无毒 α-N-草酰-α,β-的平衡混合物 (60/40)。二氨基丙酸。通过从 α-异构体开始建立相同的平衡混合物,但需要更长的时间。α- 和 γ-N-草酰基-α,γ-二氨基丁酸也经历了热诱导异构化,草酰基的 α-γ 或 γ-α 迁移。δ-N-草酰鸟氨酸和 eN-草酰赖氨酸在这些条件下不会异构化。较高同系物不发生异构化的观察结果表明反应的分子内性质。
