Different from the well-investigated enynes, transition-metal-catalyzed carbocyclization reactions of allenynes are more attractive as a result of the unique structure and versatile reactivity of allenes. Herein, we report the first cobalt-catalyzed highly chemo- and stereoselective arylative carbocyclization of 1,6-allenynes with arylboronic acids, affording five-membered carbocycles and heterocycles
与广泛研究的烯炔不同,过渡金属催化的丙二烯碳环化反应由于丙二烯独特的结构和多功能的反应活性而更具吸引力。在此,我们报告了第一个钴催化的1,6-丙炔与芳基硼酸的高度化学和立体选择性芳基化碳环化,提供了具有中等到高产率、广泛的底物范围和广泛的官能团相容性的五元碳环和杂环。此外,还进行了一些机械实验以深入了解反应过程。
