Several approaches to the synthesis of derivatives of the antifungal antibiotic TAN-950A, which is also an agonist of glutamate at hippocampal neurons, are reported. Additions of isoxazolon-4-yl anions to methyleneoxazolidinones were not useful because addition occurred predominantly through N-2. Similarly addition of the isoxazolon-4-yl radicals to model Michael acceptors occurred predominantly through
报道了几种合成抗真菌抗生素 TAN-950A 衍生物的方法,TAN-950A 也是海马神经元谷氨酸的激动剂。向亚甲基恶唑烷酮中添加异恶唑啉-4-基阴离子是没有用的,因为添加主要通过N-2进行。类似地,将异恶唑啉-4-基自由基添加到模拟迈克尔受体主要通过 N-2 发生。TAN-950A 的外消旋类似物是通过异恶唑酮曼尼希碱与乙酰氨基丙二酸酯反应或将 β-酮酯阴离子添加到脱氢丙氨酸中制备的。获得对映体纯类似物的最佳方法是通过焦谷氨酸的酰化,然后与羟胺反应。
