The reaction of a diene nitroxide precursor with dichlorophenylphosphine in a McCormac procedure afforded 1,1,3,3-tetramethyl-5-phenyl-1,2,3,4,5,6-hexahydrophospholo[3,4-c]pyrrole-5-oxide-2-oxyl. Lithiation of the protected 3-iodo-pyrroline nitroxide followed by treatment with chlorodiphenylphosphine after deprotection afforded (1-oxyl-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrol-3-yl)diphenylphosphine
二烯硝基氧前体与二氯苯基膦在 McCormac 程序中反应,得到 1,1,3,3-四甲基-5-苯基-1,2,3,4,5,6-六氢磷酰基[3,4-c]吡咯- 5-氧化物-2-氧基。受保护的3-碘-吡咯啉硝基氧的锂化,然后脱保护后用氯二苯基膦处理,得到(1-氧基-2,2,5,5-四甲基-2,5-二氢-1H-吡咯-3-基)二苯基氧化膦,还原后得到(1-氧基-2,2,5,5-四甲基-2,5-二氢-1H-吡咯-3-基)二苯基膦,X射线单晶衍射也证实了这一点测量。这种吡咯啉二苯基膦衍生物被转化为十六烷基鏻盐,它是抗肿瘤剂 MITO-CP 的类似物。
