coupling method has been developed for the single‐step generation of various γ‐amino acids and α,β‐diamino acids from α‐aminoacyl tellurides. Upon activation by Et3B and O2 at ambient temperature, α‐aminoacyl tellurides were readily converted into α‐amino carbon radicals through facile decarbonylation, which then reacted intermolecularly with acrylates or glyoxylic oxime ethers. This mild and powerful
已开发出一种新的基于自由基的偶联方法,可从α-氨酰基碲化物单步生成各种γ-氨基酸和α,β-二氨基酸。在室温下被Et 3 B和O 2活化后,α-氨基酰基碲化物很容易通过容易的脱羰作用转化为α-氨基碳原子团,然后与丙烯酸酯或乙醛氧基肟醚发生分子间反应。这种温和而有效的方法有效地整合到了加巴喷丁和天然产物(-)-甘露酸A的快速合成途径中。
