A new approach to obtain optically active unsaturated or polyunsaturated systems with a single fluorine atom in an allylic or propargylic position is reported. Central to this strategy is the high regio- and stereocontrol observed during the fluorination of propargylic alcohols allowing a short and efficient synthesis of 1. Further, simple functional group transformations gave the enals 2 and 3. These
报道了一种获得具有烯丙基或炔丙基位置的单个氟原子的光学活性不饱和或多不饱和体系的新方法。该策略的核心是在炔丙醇氟化过程中观察到的高度区域和立体控制,可实现短而高效的1合成。此外,简单的官能团转化产生了2和3的烯醛。这三种关键中间体用于制备脂肪酸代谢物的旋光单氟类似物。
