  Iridium-Catalyzed C-3 Allylation of Indoles with Allylic Alcohols Promoted by a Brønsted Acid

  摘要：

  A highly regioselective method has been developed for the allylation of indoles with an iridium catalyst. This regioselective procedure uses allylic alcohols directly as allylating agents in the presence of a catalytic amount of sulfuric acid. A wide range of indoles reacted smoothly with asymmetrical allylic alcohols to give the corresponding branched products in branched-to-linear ratios of up to 99: 1 and yields as high as 92%. A series of inorganic and organic acids were tested in this approach, and it was shown that acids with pK(a) values in acetonitrile of less than 15 are required in this iridium-catalyzed system.

  route to synthesize de novo C3-substituted benzofurans and indoles under mild conditions in moderate to good yields. Mechanistic studies revealed that the rhenium played the role of a π acid catalyst to activate the alkynes, followed by a charge-accelerated [3,3]-sigmatropic rearrangement.

  indoles and allyl acetates/alcohols. The reaction tolerates many functional groups and selectively affords the branched C3-allylated products from both α- and γ-substituted allyl substrates. It takes the advantage of the hemilabile character of the P∧N ligand. The C(sp2)–C(sp3) coupling operates via a Au(I)/Au(III) redox cycle and involves a dicationic π-allyl Au(III) complex as a key intermediate. In this
