A three-component synthesis of substituted indoles is accomplished starting from ortho-dihaloarenes through the use of a multicatalytic system consisting of an N-heterocyclic carbene palladium complex and CuI. The corresponding indole derivatives are obtained as single regioisomers in high yields of isolated product.
A system comprising TiCl 4 and t-BuNH 2 acts as a catalyst for highly regioselective hydroamination reactions of alkynes using hydrazines and at the same time a Lewis acid in the transformation of the generated hydrazones into indole derivatives, while a 1,3-diyne is converted to pyrroles using the same precatalyst.
