The Pauson-Khand reaction has in the past 50 years become one of the most common cycloaddition reactions in chemistry. Coupling two unsaturated bonds with carbon monoxide, the transformation remains limited to CO as a C 1 building block. Herein we report analogous cycloaddition reactions with nitrenes as an N 1 unit. The reaction of a nonconjugated diene with a nitrene precursor produces bicyclic bioisosteres
Pauson-Khand 反应在过去 50 年中已成为化学中最常见的环加成反应之一。将两个不饱和键与一氧化碳偶联,转化仍然限于 CO 作为 C 1积木。在此,我们报道了以氮宾作为 N 的类似环加成反应1单元。非共轭二烯与氮宾前体的反应产生常见饱和杂环的双环生物等排体,例如哌啶、吗啉和哌嗪。实验和计算机理研究支持将三线态氮烯的双自由基性质传递到 π 系统中。我们展示了该反应在药物化合物的后期功能化和可溶性环氧化物水解酶抑制剂的发现中的实用性。
