A series of isoxazolidine derivates (isomeric 2,3,5‐trisubstitutedperhydropyrrolo[3,4‐d]isoxazole‐4,6‐diones) used as anti‐inflammatory, immunosuppressive, antibacterial agent, and inhibitor for some enzymes were synthesized. These compounds were prepared by 1,3‐dipolar cycloaddition of N‐methyl maleimide and N‐phenyl maleimide with nitrones. Diastereomeric products obtained in this reaction were separated
合成了一系列异恶唑烷衍生物(2,3,5-三取代的全氢吡咯并[3,4-d]异恶唑-4,6-二酮异构体),用作抗炎药,免疫抑制剂,抗菌剂和某些酶的抑制剂。这些化合物是通过将N-甲基马来酰亚胺和N-苯基马来酰亚胺与硝酮进行1,3-偶极环加成制备的。通过柱色谱分离在该反应中获得的非对映异构体产物并重结晶。通过元素分析和光谱方法(1 H NMR,13 C NMR和FTIR)对所有合成的化合物进行表征。J.杂环化学。(2010)。
