  A new efficient strategy for the synthesis of 3‐trifluoromethyl‐indoles was developed through tandem cyclization/trifluoromethylation of 2‐alkynylanilines and Umemoto's reagent under effect of CuBr. The reaction features the use of cheap copper salt, mild reaction conditions and high yield of products. The preliminary mechanism study indicates the solvent dimethylacetamide acts as the role of dealkylation

  A new and efficient catalytic approach to the synthesis of 3-acylindoles under Pd-Cu-cocatalyzed oxidative conditions is demonstrated. tert-Butyl hydroperoxide (TBHP) acts not only as the oxidant, but also as an oxygen source in the approach. The process allows quick and atom-economical assembly of 3-acylindoles from readily available starting materials and tolerates a broad range of functional groups

  A palladium-catalyzed tandem cyclization/C-H functionalization of two alkynes was accomplished to construct a series of polycyclic functionalized indoles. A range of internal alkynes bearing synthetically useful functional groups were tolerated. A good regioselectivity was observed when alkyl-substituted alkynes were introduced into the reaction system, and a single product was obtained. Molecular oxygen was used as the terminal oxidant in the approach, rendering the reaction more sustainable.
• Application of FeCl3/Diorganyl Diselenides to Cyclization of o-Alkynyl Anilines: Synthesis of 3-Organoselenyl-(N-methyl)indoles

  In this manuscript we described the FeCl3/diorganyl diselenides promoted intramolecular cyclization of o-alkynyl anilines, as an alternative for the construction of functionalized 3-organoselenyl indoles. The cyclization reactions proceeded smoothly at room temperature in the presence of air giving the 3-organoselenyl indoles in good yields. Additionally, the 3-organoselenyl indoles proved to be quite useful as synthetic intermediates for the construction of more functionalized indole units through a selenium-lithium exchange reaction followed by trapping the lithium intermediate with different electrophiles.
