Boron trifluoride-mediated transformation of tetrahydrofuran to corresponding N-aryl-substituted pyrrolidines is conducted under mild reaction conditions, providing a practical synthetic method with reasonable yields. Computational studies confirmed the reaction mechanism involving a fast Lewis acid-assisted ring-opening step, followed by the 7-membered intermediate formation and a ringclosing process
在温和的反应条件下进行三氟化硼介导的四氢呋喃向相应的N-芳基取代的吡咯烷的转化,提供了一种实用的合成方法,收率合理。计算研究证实了该反应机理涉及快速路易斯酸辅助的开环步骤,随后是7元中间体的形成和作为速率确定步骤的闭环过程。
