impact sensitivity, more research into the safety profiles of cage scaffolds is required. Therefore, the impact sensitivity and thermal decomposition behavior of judiciously selected starting materials and synthetic intermediates of cubane, bicyclo[1.1.1]pentane (BCP), and bicyclo[2.2.2]octane (BCO) were evaluated via hammer test and sealed cell differential scanning calorimetry, respectively. Iodo‐substituted
随着对用于生物活性分子发现的笼形基序的兴趣不断增强,并且最近披露了1,4-古巴-二羧酸的撞击敏感性,需要对笼形脚手架的安全性进行更多的研究。因此,通过锤击试验和密封电池评估了明智选择的起始原料和古巴,双环[1.1.1]戊烷(BCP)和双环[2.2.2]辛烷(BCO)的合成中间体的冲击敏感性和热分解行为差示扫描量热法。发现碘取代的体系对冲击更敏感,而羟甲基取代导致更快的热分解。Cubane更有可能对这些取代基具有冲击敏感性,其次是BCP,而所有BCO均无反应。
