for the palladium-catalyzeddecarboxylative 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

A highly efficient palladiumcatalyzed decarboxylative allylic rearrangement of alloc indoles has been developed. This can also be combined with a Suzuki–Miyaura cross-coupling reaction in a single pot transformation. Substituted alloc groups and benzylic variants have also been demonstrated alongside promising initial results on the enantioselective variant.
