Nine methyl esters of cyclic amino-group substituted carboxylic acids related to glycine, alanine or β-alanine were subjected to electrochemicalfluorination. This afforded the corresponding perfluoroacid fluorides together with cleavage products in fair yields. As cyclic amino-substituents, pyrrolidino-, morpholino-, piperidino-, hexamethyleneimino- and N′-methyl-piperazinyl-groups were investigated
对与甘氨酸,丙氨酸或β-丙氨酸有关的环状氨基取代的羧酸的九种甲酯进行电化学氟化。这样以合理的产率得到了相应的全氟氟化物和裂解产物。作为环状氨基取代基,研究了吡咯烷基,吗啉代,哌啶子基,六亚甲基亚氨基和N'-甲基哌嗪基。未观察到环化副产物的形成,这与脂族二烷基氨基取代的羧酸的氟化形成对比。从这样的2-环氨基丙酸甲酯[环氨基:吡咯烷基,吗啉代或哌啶子基],与全氟酸氟化物一起得到全氟甲基酯,产率为1-2%和14-29。 % 分别。前一种化合物的形成归因于庞大的环状氨基的阻断作用。报告了所获得的新化合物的物理性质及其光谱(19 F NMR,质量和IR)数据。
