以氟化钾(KF)和六氟异丙醇为催化剂,研究了铜催化的H-F插入α-重氮羰基化合物的反应。在温和的条件下获得复杂的α-氟羰基衍生物,并且该方法易于适用于[18 F]KF的放射性同位素示踪。这种后期策略为18F标记的生物分子提供了一条有吸引力的途径。
The copper-catalyzed H–F insertion into α-diazocarbonyl compounds is described using potassium fluoride (KF) and hexafluoroisopropanol. Access to complex α-fluorocarbonyl derivatives is achieved under mild conditions, and the method is readily adapted to radiofluorination with [18F]KF. This late-stage strategy provides an attractive route to 18F-labeled biomolecules.
