Irradiation of indole-3-acetic acid (2) in the presence of pyrimido[5, 4-g]pteridine N-oxide (1a) results in the formation of indole-3-carboxyaldehyde (3) as a major product. A reaction sequence for the photooxidative decarboxylation is presented and discussed in connection with the biological transformation of 2 to 3 in plants.
在
吡啶唑[5, 4-g]
哌啶N-氧化物(1a)的存在下,对
吲哚-3-
乙酸(2)进行辐照,可以生成
吲哚-3-羧醛(3)作为主要产物。提出并讨论了光氧化脱羧反应的反应序列,并与植物中2转化为3的
生物转化过程相关联。
