摘要

摘要

En 中文
顺序偶联和环化反应使含有多反应位点的2个线性底物能够实现有用环状化合物的单步合成;然而,如果反应位点高度活泼,则容易发生过度反应。尽管微流合成可以防止过度反应,但需要仔细优化多个变量。在此,我们通过2个含高度活泼位点的线性底物的顺序偶联和环化反应,优化了环状磺酰胺的微流合成。基于单变量一次优化法(one-variant-at-a-time-based approach)的传统方法揭示了变量与环状磺酰胺收率之间的非线性相关性,最优条件下的收率为90%。随后采用基于贝叶斯优化(BO)的方法进行再优化,确定了显著不同的最优条件,使产物收率达到94%。为探究影响基于贝叶斯优化方法最优条件的关鍵因素,进行了额外的实验和模拟。
