selectivity and favorable pharmacokinetic properties. Here, we report an operationally simple and broadly applicable approach for the 18F-fluorination of unprotected peptides via a new radiosynthon, [18F]fluoro-4-(vinylsulfonyl)benzene. This reagent demonstrates excellent chemoselectivity at the cysteine residue and rapid 18F-labeling of a diverse scope of peptides to generate stable thioether constructs
放射性标记的基于肽的分子成像探针利用大生物制剂和小分子的优势,提供出色的选择性和有利的药代动力学特性。在这里,我们报告了一种操作简单且广泛适用的方法,用于通过新的放射性合成子 [ 18 F] 氟-4-(乙烯基磺酰基)苯对未受保护的肽进行18 F-氟化。该试剂在半胱氨酸残基处表现出出色的化学选择性,并对多种肽段进行快速18 F 标记,以生成稳定的硫醚构建体。

unusual concerted nucleophilicaromaticsubstitutionreaction (CSNAr) that is not limited to electron-poor arenes, because it does not proceed via a Meisenheimer intermediate. We show a phenol deoxyfluorination reaction for which CSNAr is favored over a stepwise displacement. Mechanistic insights enabled us to develop a functional group–tolerant 18F-deoxyfluorination reaction of phenols, which can be used
