异戊二烯片段是萜类天然产物的典型成分,萜类天然产物是一个多样化的家族,包含许多具有不同生物特性的成员。相比之下,氟化芳烃和多氟化芳烃构成了一类重要的人类分子,与材料、农业和制药工业高度相关。虽然烯丙基化化学已得到很好的发展,但有效的异戊二烯化策略却尚未出现。在这里,我们描述了光催化脱氟异戊二烯化,这是一种强大的方法,可以提供同时具有异戊二烯基和氟化芳烃功能的“混合分子”。该方法涉及在非常温和的条件下直接进行异戊二烯基转移,表现出优异的官能团耐受性和相对较短的反应时间(<4小时),是迄今为止开发的最快的光催化C-F官能化。此外,该策略还可以扩展到包括烯丙基和香叶基(10 个碳片段)转移。另一个突出的发现是主要产物的区域选择性从对位 C-F 功能化转变为邻位 C-F 功能化,依赖于试剂。
The prenyl fragment is the quintessential constituent of terpenoid natural products, a diverse family which contains numerous members with diverse biological properties. In contrast, fluorinated and multifluorinated arenes make up an important class of anthropogenic molecules which are highly relevant to material, agricultural, and pharmaceutical industries. While allylation chemistry is well developed, effective prenylation strategies hav e been less forthcoming. Herein, we describe the photocatalytic defluoroprenylation, a powerful method that provides access to “hybrid molecules” that possess both the functionality of a prenyl group and fluorinated arenes. This approach involves direct prenyl group transfer under very mild conditions, displays excellent functional group tolerance, and relatively short reaction times (<4 h), which is the fastest photocatalytic C–F functionalization developed to date. Additionally, the strategy can be extended to include allyl and geranyl (10 carbon fragment) transfers. Another prominent finding is a reagent dependent switch in regioselectivity of the major product from para to ortho C–F functionalization.
