An efficient synthesis ofenantiopure 2,3-aziridino-γ-lactones from azetidin-2-ones is described. Acid-catalyzed tandem intramolecular azetidinone ring opening followed by aziridine ring formation via elimination of a mesylate group is the key step in this synthesis. 2,3-Aziridino-y-lactones are important precursors for biologically important glulamic acid derivatives.
描述了一种从 azetidin-2-ones 有效合成对映体纯 2,3-aziridino-γ-内酯的方法。酸催化串联分子内氮杂环丁酮开环,然后通过消除甲磺酸酯基团形成氮丙啶环是该合成中的关键步骤。2,3-Aziridino-y-内酯是生物学上重要的谷氨酸衍生物的重要前体。
