Grignard reaction of nitrone 1 with arylmagnesium bromides afforded different pyrrolidine nitroxide radicals 2a-f, which were converted further to spin labelled ebselen 6, saccharine 11, phenols 5, 12, 13, quinone 16 and heterocycles 20, 21, 24. Paramagnetic sulfonyl chlorides 7a, 7b, 9a and methanethiosulfonate 25d capable of amino and thiol labelling, respectively, were also prepared.
腈酮 1 与芳基溴化镁发生格氏反应,可得到不同的吡咯烷亚硝基 2a-f,再进一步转化为自旋标记的依布硒 6、糖精 11、酚 5、12、13、醌 16 和杂环 20、21、24。此外,还制备了顺磁磺酰氯 7a、7b、9a 和甲硫磺酸盐 25d,它们分别能对氨基和硫醇进行标记。
