6,6,6-2H3-2E-Hexenal, leaf-aldehyde, has been synthesized in 45% yield and 99.3% purity by reaction of 3,3,3-2H3-n-propyl magnesium bromide with an ethereal solution of 3-trimethylsiloxy-2-propenal (3) prepared in situ. This new one pot procedure alleviates the need to isolate (3) and should prove useful in the synthesis of other E-α,β-unsaturated aldehydes.
通过 3,3,3-2H3- 正丙基溴化镁与原位制备的 3-三甲基硅氧基-2-丙烯醛(3)的乙醚溶液反应,合成了 6,6,6-2H3-2E-己烯醛(叶醛),收率为 45%,纯度为 99.3%。这一新的一锅法简化了(3)的分离过程,在合成其他 E-α,β-不饱和醛类化合物时也会很有用。
