established for the construction of γ-azido amino acids under visible light. This transformation features mild and redox-neutral conditions, affording a series of amino esters with excellent chemoselectivity. Preliminary mechanistic studies revealed that the addition of an oxyalkyl radical to imine is likely the rate-determining step. The obtained azido-containing amino esters could be successfully converted
建立了基于乙醛酸酯基的亚胺,烯醇醚和TMSN 3的三组分和极性相反的加成级联反应,用于在可见光下构建γ-叠氮基氨基酸。这种转化具有温和的氧化还原中性条件,提供了一系列具有优异化学选择性的氨基酯。初步的机理研究表明,向亚胺中添加一个氧烷基可能是决定速率的步骤。所获得的含叠氮基的氨基酯可以成功地转化为各种有价值的结构单元。
