A novel synthetic method for 2,4-alkadienoic acids from allylic alcohols and 2,2,2-trifluoroethyl phenyl sulfoxide is described which involves the in situ Claisen rearrangement facilitated by the fluorine. This method was applied to the stereocontrolled synthesis of pellitorine, a natural insecticide.
一种从烯丙醇和2,2,2-三氟乙基苯亚砜合成2,4-二烯酸的新颖合成方法被描述出来,该方法利用氟原子现场促进的克莱森重排。这种方法被应用于天然杀虫剂苦艾素的立体控制合成。
