We report the synthesis of the alcohol (–)-7-epichrysanthenol (3a) by a two-step route from (+)-3,7-epoxypinan-2-ol, a by-product of permanganate oxidation of (–)-α-pinene; (3a), which can be oxidised to chrysanthenone, yields quantitatively, by a thermal rearrangement, the aldehyde (+)-(1R)-1-formyl-2,2,4-trimethylcyclohex-3-ene (5) in an optically active form.
我们报告了从(+)-3,7-环氧ep-2--2-醇((-)-的高锰酸盐氧化的副产物)分两步合成醇(-)-7-表三烯酚(3a)的方法。 α-pine烯; (3a)可以被氧化成菊花烯酮,通过热重排定量地生成醛(+)-(1 R)-1-甲酰基-2,2,4-三甲基环己-3-烯(5)光学活性形式。
