[reaction: see text] The formal synthesis of the ocular age pigment A2-E was achieved by the efficient one-pot preparation of the substituted pyridine, which involves the aza-6pi-electrocyclization of the Schiff base derived from (E)-3-carbonyl-2,4,6-trienal followed by oxidation.
[反应:见正文]通过有效的一锅法制备取代的吡啶,可以完成眼龄色素A2-E的正式合成,其中涉及从(E)-3衍生的席夫碱的aza-6pi电环化-羰基-2,4,6-三烯醛,然后氧化。
