A photoinduced palladium-catalyzed 1,2-carbofunctionalization of conjugated dienes has been developed. This mild modular approach, which does not require employment of exogeneous photosensitizers and external oxidants, allows for efficient and highly regio- and ste-reoselective synthesis of a broad range of allylic amines from readily available 1,3-dienes, alkyl iodides, and amines. Employment of O-
已开发出光诱导钯催化的共轭二烯的 1,2-碳功能化。这种温和的模块化方法不需要使用外源光敏剂和外部氧化剂,允许从容易获得的 1,3-二烯、烷基碘和胺中高效且高度区域和立体选择性地合成各种烯丙胺. 还证明了使用 O-和 C-亲核试剂进行烷氧基化和二烷基化产物。推定的 π-烯丙基钯自由基 - 极性交叉路径被认为是该三组分耦合过程中的关键事件。该协议的实用性因其在几种含胺药物的衍生化中的应用而突出。
