  • Synthesis of 3-alkyl-6-methyl-1,2,4,5-tetrazines <i>via</i> a Sonogashira-type cross-coupling reaction

    alkynes. The preparation of the starting reagents has also been optimized. The alkynyl products have been used as intermediates for the synthesis of dialkyl-tetrazines through a sequence of hydrogenation and re-oxidation with unprecedented yields. The synthetic applicability of this new approach is showcased through the preparation of several unnatural amino acids bearing alkynyl- and alkyl-1,2,4,5-tetrazine
    1,2,4,5-四嗪已成为化学生物学中极为有用的工具。然而,一些具有挑战性的底物如不对称双取代的烷基四嗪的合成仍然是这类化合物广泛使用的限制。本文中,我们基于3-溴-6-甲基-1,2,4,5-四嗪和3-溴-6-苯基-1,2,4,5-四嗪的Sonogashira偶联描述了制备这些化合物的有效途径与末端炔烃。起始试剂的制备也已优化。炔基产物已被用作中间体,通过一系列加氢和再氧化反应以前所未有的产率合成二烷基四嗪。通过制备几种带有炔基和烷基1,2,4,5-四嗪片段的非天然氨基酸,展示了这种新方法的合成适用性。

    inverse electron demand Diels–Alder reaction (DAinv) and tetrazine substituted fluorophores can exhibit fluorogenic properties. Herein, we report the synthesis of a palette of novel fluorogenic tetrazine dyes derived from widely-used fluorophores that cover the entire emission range from green to far-red. We demonstrate the power of the new fluorogenic probes in fixed and live cell labeling experiments
    用于生物正交标记化学的荧光探针对于减少荧光显微镜成像中的背景信号非常有益。1,2,4,5-四嗪是生物正交逆电子需求Diels–Alder反应(DA inv)的底物,四嗪取代的荧光团可以表现出荧光性质。在这里,我们报告了从广泛使用的荧光团衍生的新型荧光四嗪染料调色板的合成,该荧光团覆盖了从绿色到远红色的整个发射范围。我们在固定和活细胞标记实验中展示了新型荧光探针的功能,并展示了在无清洗条件下使用基于四嗪的探针进行细胞内活细胞蛋白质成像的第一个例子。

    A Ag-mediated Pd-catalyzed cross-coupling method for 3-bromo-1,2,4,5-tetrazine with boronic acids is presented. Electronic modification of the 1,1′-bis(diphenylphosphine)ferrocene (dppf) ligand was found to be crucial for good turnover. Using this fast method, a variety of alkyl-, heteroatom-, and halide-substituted aryl- and heteroaryl-tetrazines were prepared (29 examples, up to 87% yield).

    aggregation-induced emission (AIE) characters and multicolor emissions after bioorthogonal reaction with strained dienophiles. Manipulating the π-bridge in the fluorophore skeleton allows fine-tuning of the emission wavelength and influences the AIE-active properties. With these probes, we succeeded in no-wash fluorogenic protein labeling and mitochondria-selective bioorthogonal imaging in live cells.
    开发了一系列萘酰亚胺-四嗪作为生物正交荧光探针,在与应变的亲双烯体进行生物正交反应后,可以产生显着的荧光增强、显着的聚集诱导发射(AIE)特征和多色发射。操纵荧光团骨架中的 π 桥可以微调发射波长并影响 AIE 活性特性。使用这些探针,我们成功地在活细胞中进行免洗荧光蛋白标记和线粒体选择性生物正交成像。

    fluorescence turned off through a bioorthogonal iEDDA cycloaddition with a strained alkene, showing for the first time the detection and reactivity of intrinsically fluorescent tetrazines in a biologically relevant context. The synthesis and characterization of fluorescent tetrazine ethers with bioorthogonal applicability pave the way for the generation of useful compounds for both detection and bioconjugation
    一组具有三个不同取代的 3-溴-1,2,4,5-四嗪已被用作通过亲核芳族取代对小分子进行后期功能化的试剂。对所得产物的光谱研究证明,四嗪醚本质上是荧光的。这种荧光在与应变烯烃的逆电子需求 Diels-Alder (iEDDA) 环加成反应中消失。四嗪-苯酚醚非常有趣,因为它们可以进行快速的 iEDDA 反应,具有与生物正交连接相容的二级速率常数 ( k 2 )。作为展示,L-酪氨酸用 3-溴-6-甲基-1,2,4,5-四嗪衍生并与肽药物奥曲肽偶联。该肽在细胞流式细胞仪中被检测到,其荧光通过与应变烯烃的生物正交 iEDDA 环加成关闭,首次显示了在生物学相关环境中固有荧光四嗪的检测和反应性。具有生物正交适用性的荧光四嗪醚的合成和表征为产生用于体内检测和生物偶联的有用化合物铺平了道路。
