reactions are largely underrepresented in the toolbox of chemoselective ligations despite their tremendous potential, particularly in chemical biology and biochemistry. In this respect, we have investigated in full detail the fluorescence behaviour of the azaphthalamide, a scaffold which is generated through a hetero‐Diels–Alder reaction of 5‐alkoxyoxazole and maleimide derivatives under mild conditions
尽管有巨大的潜力,但在化学选择性连接工具箱中,荧光反应在很大程度上没有得到很好的体现,特别是在化学生物学和生物化学领域。在这方面,我们已经详细研究了氮杂邻苯二甲酰胺的荧光行为,该骨架是由5-烷氧基恶唑和马来酰亚胺衍生物在与肽化学等相容的温和条件下通过杂色-狄尔斯-阿尔德反应生成的。这种荧光标记策略的范围和局限性通过四个不同的应用进行了检查,这些应用的目标是酶活性或生物正交反应。
