prepared several pyridine‐ and pyrimidine‐based self‐immolative spacer groups to evaluate the significance of the resonance energy of the spacer aromatic ring on the kinetics of 1,4‐ and 1,6‐elimination reactions, which govern spacer disassembly. Subsequently, we relied on a photoactivation procedure to accurately analyze the disassembly kinetics. Beyond providing new results that are relevant for deriving
我们准备了几个基于吡啶和嘧啶的自消旋间隔基团,以评估间隔基芳环共振能对控制间隔基拆卸的1,4-和1,6-消除反应动力学的重要性。随后,我们依靠光活化程序来准确分析拆解动力学。除了提供与得出定量的结构-性质关系相关的新结果外,本文还证明了pH值可以用作有效参数,以精确控制初始活化后自焚性间隔基的分解时间。
