triazolopyridine formation strategy is reported here for the first time in which hypochlorous acid (HOCl) mildly and efficiently promotes the formation of 1,2,4-triazolo[4,3-a]pyridines NT1-NT6 from various 2-pyridylhydrazones N1-N6. N6, a rhodol-pyridylhydrazone hybrid, was developed into a fluorescent probe for the selective detection of HOCl, and successfully applied to probe endogenous HOCl in living cells
摘要三唑并吡啶是一种重要的稠环化合物。首次报道了HOCl促进的三唑并吡啶的形成策略,其中次氯酸(HOCl)温和有效地促进了由各种2-吡啶基azoN1-N6。N6是一种Rhodol-吡啶基hydr杂化物,已开发成为可选择性检测HOCl的荧光探针,并成功地应用于原位实时检测活细胞和斑马鱼中的内源性HOCl。当前的分子内环化反应是选择性的并且是原子经济的,从而不仅为方便地合成三唑并吡啶提供了重要的方法,而且为复杂生物系统中内源性HOCl的灵敏,选择性和生物相容性检测提供了通用策略。
