for the palladium-catalyzed decarboxylative C3-allylation and C3-benzylation of indoles, starting from the corresponding N-alloc and N-Cbz indoles, respectively, is reported. This chemistry provides ready access to a wide range of functionalized indolenines in good to excellent yields. A tandem process, wherein the palladium catalyzed allylation chemistry is coupled with a Mizoroki–Heck reaction, offers
分别从相应的N- alloc 和N- Cbz 吲哚开始,钯催化的吲哚脱羧 C3-烯丙基化和 C3-苄基化的一组通用方法被报道。这种化学反应可以很容易地获得各种功能化的假吲哚,收率非常好。一种串联工艺,其中钯催化的烯丙基化化学与 Mizoroki-Heck 反应相结合,为肉桂化产品提供了一条简单的途径。
