    Highly Efficient and Broad-Scope Protocol for the Preparation of 7-Substituted 6-Halopurines via N9-Boc-Protected 7,8-Dihydropurines
    摘要:
    高产率可获得的9-Boc-6-氯嘌呤几乎可以定量地被THF-BH3复合物还原。所得到的9-Boc-7,8-二氢嘌呤衍生物相比于相应的9-三苯甲基嘌呤更加稳定,并且可以顺利地进行N7-烷基化、酰基化或作为N-亲核试剂参与共轭加成。使用三氟乙酸脱保护后,再经MnO2氧化,可获得高产率的N7-取代嘌呤。整个烷基化、脱保护和氧化的序列可以在使用色谱法仅对最终的N7-取代嘌呤进行纯化的条件下,利用粗中间体完成。

  • Chelator-Accelerated One-Pot ‘Click’ Labeling of Small Molecule Tracers with 2-[18F]Fluoroethyl Azide
    作者:Eva Galante、Bent Schoultz、Matthias Koepp、Erik Årstad
    DOI:10.3390/molecules18055335
    日期:——
    2-[18F]Fluoroethyl azide ([18F]FEA) can readily be obtained by nucleophilic substitution of 2-azidoethyl-4-toluenesulfonate with [18F]fluoride (half-life 110 min), and has become widely used as a reagent for ‘click’ labeling of PET tracers. However, distillation of [18F]FEA is typically required, which is time-consuming and unpractical for routine applications. In addition, copper(I)-catalyzed cycloaddition of [18F]FEA with non-activated alkynes, and with substrates containing labile functional groups, can be challenging. Herein, we report a highly efficient and practical ligand-accelerated one-pot/two-step method for ‘click’ labeling of small molecule tracers with [18F]FEA. The method exploits the ability of the copper(I) ligand bathophenanthrolinedisulfonate to accelerate the rate of the cycloaddition reaction. As a result, alkynes can be added directly to the crude reaction mixture containing [18F]FEA, and as cyclisation occurs almost immediately at room temperature, the reaction is tolerant to labile functional groups. The method was demonstrated by reacting [18F]FEA with a series of alkyne-functionalized 6-halopurines to give the corresponding triazoles in 55–76% analytical radiochemical yield.
    2-[18F]氟乙基叠氮化物([18F]FEA)可以通过用[18F]氟化物(半衰期110分钟)对2-叠氮乙基-4-甲苯磺酸酯进行亲核取代反应获得,并已广泛用于PET示踪剂的“点击”标记。然而,通常需要对[18F]FEA进行蒸馏,这既耗时又不适合日常应用。此外,[18F]FEA与未活化的炔烃及含有活泼官能团的底物之间的铜(I)催化的环加成反应也可能存在挑战。在此,我们报告了一种高效且实用的配体加速一锅两步法,用于小分子示踪剂的“点击”标记,使用[18F]FEA。该方法利用了铜(I)配体巴佛芬胺二磺酸盐加速环加成反应速率的能力。因此,可以将炔烃直接加入含有[18F]FEA的粗反应混合物中,并且由于环化反应几乎在室温下立即发生,反应能够耐受活泼官能团。该方法通过将[18F]FEA与一系列炔基功能化的6-卤代嘌呤反应,产生相应的三唑,分析放射化学产率为55-76%。

    A practical and efficient H/D exchange method for selective deuteration of terminal alkynes was disclosed. The reaction was simply performed with CF3COOAg as catalyst at room temperature, affording products with high level of deuterium incorporation. The excellent site-selectivity and promising functional group tolerance of this protocol enabled deuteration of pharmaceuticals and nature product derivatives
