spacer-technique to develop dendritic and polymeric self-immolative molecular systems that can disassemble through a domino-like mechanism upon a stimulus event. In this report, we study the disassembly of a system that can disintegrate through para- and ortho-azaquinone-methide eliminations. The disassembly was evaluated with molecules that undergo single 1,6- or 1,4-elimination and with molecules that
消除氮杂醌是一个强大而有效的反应,可用于拆解前药系统中的间隔基。我们和其他人已经使用间隔子技术来开发树突状和聚合的自消灭分子系统,这些系统可以在刺激事件发生时通过类似多米诺的机制进行分解。在本报告中,我们研究了可通过对位和邻位氮杂醌甲基化物消除而分解的系统的分解。用经历单个1,6-或1,4-消除的分子和经历双重1,6-和1,4-消除的分子评估拆卸。在生理条件下,1,6-消除比1,4-消除略快。这项研究揭示了前药系统的拆卸行为。
