摘要: 将4-氧-2,2,6,6-四甲基哌啶-1-氧自由基(TMPO)与3种植物生长素拼接在一起,合成了相应的腙,以研究TMPO对生长素活性的影响。所得化合物的结构通过IR、ESR、元素分析或MS加以证实。初步生物活性测定表明,与母体相比不仅对绿豆幼苗的生长促进作用无影响,在一定条件下还增强了促进生长的活性。

Abstract: Three spin-labelling auxins have been synthesized by reaction of 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl(TMPO) with p-chlorophenoxyacetic acid, 1-naphthylacetic acid and 2,4-dichlorophenoxyacetic acid respectively. The structures of the labelling auxins were confirmed by IR, ESR/MS measurements and elemental analysis. The preliminary bioassays of the compounds indicated that they retain the original plant regulating property.

Key words: auxin, spin-labelling, synthesis, bioactivity
