标记和检测5-甲酰嘧啶对于了解其生物学功能至关重要。在本文中,我们描述了可见光触发且无催化剂的反应,其中5-甲酰基胞苷RNA可以在商业蓝色LED光的照射下用2-硫代苯胺选择性标记以产生荧光5-(苯并噻唑-2-基)胞苷。
Labelling and detecting 5‐formylpyrimidine is essential to understand its biological function. Herein, we describe a visible‐light triggered and catalyst‐free reaction in which 5‐formylcytidine RNA can be selectively labelled with 2‐thioaniline under the irradiation of a commercial blue LED light to generate fluorogenic 5‐(benzothiazol‐2‐yl) cytidine.
