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

Given the prevalence of the indole nucleus in biologically active compounds, the direct C3-functionalization of 2,3-disubstituted indoles represents an important problem. Described is a general, high-yielding method for the palladium-catalyzed beta-allylation of carba- and heterocycle fused indoles, including complex natural product substrates.
