Site-selective functionalization of saturated N-heterocycles such as pyrrolidines is a central topic in organic synthesis and drug discovery. We herein report the sulfur-assisted rhodium(III)-catalyzed sp C-H amidation of pyrrolidines with dioxazolones as amidating agents. The amenability of the thioamide directing group is elucidated by a series of control experiments.
饱和氮杂环(如吡咯烷)的位点选择性官能团化是有机合成和药物发现中的核心课题。我们在此报告了以二恶唑酮为酰胺化试剂,硫辅助铑(III)催化的吡咯烷sp C-H酰胺化反应。通过一系列对照实验阐明了硫代酰胺导向基团的适用性。
