several limitations in both chemical yields and enantioselectivities of the fluorinated products. We present here the background of our personal story of the enantioselectivefluorination reaction and some successful applications of the methods to the design and synthesis of biologically active products. Two novel approaches using cinchonaalkaloid/Selectfluor® combinations and chiral ligands/metal complexes

A novel [18F]NF reagent and two novel radiochemical transformations have been developed: [18F]NFSi has been prepared from sodium dibenzenesulfonimide and reacted in the presence of silyl enol ethers and allylsilanes to deliver labelled fluorinated ketones and allylic fluorides respectively; the radiosynthesis of the fluorinated A ring of vitamin D3 has also been completed with success.
一种新型[18F]NF 试剂和两种新型放射化学转化方法已经研制成功:以二苯磺酰亚胺钠为原料制备了[18F]NFSi,并在硅基烯醚和烯丙基硅烷存在下发生反应,分别生成了标记的氟化酮和烯丙基氟化物;维生素 D3 的氟化 A 环的放射合成也已成功完成。
