A universal strategy to control tetrazine reactivity in the inverse electron-demand Diels–Alder (IEDDA) reaction was developed as “Clip to Click”. Incorporating a chemical bridge into 3,6-diphenyl-1,2,4,5-tetrazine (macrocyclic tetrazine) rendered it unreactive toward trans-cyclooctene. A computational study revealed that the unreactive property of macrocyclic tetrazines is mainly due to the high distortion
一种在逆电子需求 Diels-Alder (IE
DDA) 反应中控制四嗪反应性的通用策略被开发为“Clip to Click”。将
化学桥结合到 3,6-diphenyl-1,2,4,5-tetrazine(大环四嗪)中使其对反式-环
辛烯无反应性。一项计算研究表明,大环四嗪的非反应性主要是由于四嗪的高畸变能。我们证明了大环接头的切割(“剪辑”)可以激活四嗪部分以进行 IE
