A highly regioselective synthesis of allylic amines based on a tungsten-catalyzed allylic amination has been developed. This protocol, which is catalyzed by commercially available W(CO)3(MeCN)3 and 4,4′-di-tert-butyl-2,2′-bipyridine, permits the formation of synthetically useful branched allylic N-aryl- and N-alkylamines in moderate to good yields with a >20:1 branched/linear ratio under mild conditions
已经开发出基于钨催化烯丙胺化的烯丙胺的高度区域选择性合成。该方案由市售的 W(CO) 3 (MeCN) 3 和 4,4'-二叔丁基-2,2'-联吡啶催化,允许在温和条件下以中等至良好的产率形成合成有用的支化烯丙基 N-芳基胺和 N-烷基胺,支化/直链比例 >20:1。不含贵金属的催化系统补充了由 Ir 或 Rh 络合物催化的传统烯丙胺化反应。
