通过合成4-HMDEPMPO硝酮(5-二乙氧基磷酰基-4-),建立了制备在C-4上官能化的DEPMPO硝酮(5-二乙氧基磷酰基-5-甲基-1-吡咯啉-N-氧化物)衍生物的一般合成路线。硝基化合物1还原制得的羟甲基-5-甲基-1-甲基-1-吡咯啉-N-氧化物)。(4 R *,5 S *)-4-HMDEPMPO已成功与其次要的非对映异构体分离,可用于生成各种取代的类似物。其中,4-NHSDEPMPO,5-二乙氧基磷酰基-4-琥珀酰亚胺基氧基羰基氧基甲基-5-甲基-1-吡咯啉-N-氧化物构成NH 2。-反应性前体,用于进一步偶联至相关部分,例如靶向基团,标记或药物。由4-NHSDEPMPO合成了生物素化的硝酮,为靶向递送应用提供了新的视角。简短研究了这些4-HMDEPMPO类似物的(4 R *,5 S *)异构体的俘获行为,证明它们与DEPMPO一样能检测超氧化物。对于每种异构体,仅获得一种非对
