    Synthesis of18F-Labelled β-Lactams by Using the Kinugasa Reaction
    摘要:
    AbstractOwing to their broad spectrum of biological activities and low toxicity, β‐lactams are attractive lead structures for the design of novel molecular probes. However, the synthesis of positron emission tomography (PET)‐isotope‐labelled β‐lactams has not yet been reported. Herein, we describe the simple preparation of radiofluorinated β‐lactams by using the fast Kinugasa reaction between 18F‐labelled nitrone [18F]‐1 and alkynes of different reactivity. Additionally, 18F‐labelled fused β‐lactams were obtained through the reaction of a cyclic nitrone 7 with radiofluorinated alkynes [18F]‐6 a,b. Radiochemical yields of the Kinugasa reaction products could be significantly increased by the use of different CuI ligands, which additionally allowed a reduction in the amount of precursor and/or reaction time. Model radiofluorinated β‐lactam‐peptide and protein conjugates ([18F]‐10 and 18F‐labelled BSA conjugate) were efficiently obtained in high yield under mild conditions (aq. MeCN, ambient temperature) within a short reaction time, demonstrating the suitability of the developed method for radiolabelling of sensitive molecules such as biopolymers.

[18F]MEL054 was prepared by an automated two-step radiosynthesis, comprising of the preparation of 4-[18F]fluorobenzaldehyde from 4-formyl-N,N,N-trimethylanilinium triflate, followed by reductive alkylation with 2-(2-oxo-2-piperazin-1-ylethyl)isoindolin-1-one. 4-[18F]Fluorobenzaldehyde was prepared on a GE TRACERlab FXFN module in 68 ± 8 % radiochemical yield (RCY, non-decay corrected), purified by a Sep-Pak Plus C18 cartridge and eluted into the reactor of an in-house modified Nuclear Interface [18F]FDG synthesis module for the subsequent reductive alkylation reaction. HPLC purification produced [18F]MEL054 in a collected RCY of 34 ± 9 % (non-decay corrected), the total preparation time (including Sep-Pak Plus C18 and HPLC purification) did not exceed 105 min. The radiochemical purity of [18F]MEL054 was greater than 99 % with a specific radioactivity of 71–119 GBq μmol–1 and [18F]MEL054 remained stable in saline solution (>98 %) after 3 h.

    Fluorination of aromatic compounds by nucleophilic displacement of trimethylanilinium salts by fluoride is a commonly used reaction for radiotracer synthesis. Though the liberated trimethylamine is thought to be an excellent leaving group for this type of SNAr reaction, scattered reports show that amine demethylation (reverse Menschutkin reaction) sometimes dominates over substitution, particularly when
    通过氟化物的三甲基苯胺盐的亲核置换来氟化芳族化合物是放射性示踪剂合成的常用反应。尽管释放的三甲胺被认为是此类S N Ar反应的极佳离去基团,但零星的报道表明,胺的脱甲基作用(孟舒特金逆反应)有时优于取代,尤其是当相对富电子的氟代芳烃成为所需的靶标时。在这里,我们提供了三甲基苯胺脱甲基和取代的系统实验和理论研究。这些研究的结果突显了该离去基团在氟芳烃合成中的局限性,对于设计具有铵阳离子的亲核氟化剂具有重要意义。
