An efficient method for the synthesis of 2-substitutedindoles via a diboron/base promoted tandem reductive cyclization of o-alkynylnitroarene under Au catalysis conditions has been disclosed. This reaction is efficient and convenient, affording 2-substitutedindoles with broad functional groups tolerance and excellent yields.

Various 2-substitutedindoles were prepared by heteroannulation of o-iodoanilines and terminal alkynes in a one-pot reaction with a Pd(II)–NaY zeolite catalyst. The product formation largely depended on the solvent, base, and reaction temperature. The recycled catalyst showed good reusability in the heteroannulation reaction.
In certain embodiments, the invention is directed to a method for treating a protein folding disorder comprising administering to a subject a compound of the formulas disclosed. In preferred embodiments, the compounds are bis-indole compounds.

[GRAPHICS]A general method for the synthesis of 2-aryl and 2-heteroaryl indoles from aryl iodides and 1-alkynes through a domino copper-catalyzed process is reported. The best results have been obtained with [Cu(phen)(PPh3)(2)]NO3 in the presence of K3PO4 in toluene or dioxane at 110 degreesC. 2-Aryl and 2-heteroaryl indoles can also be isolated in good yields by using catalysts derived from CuI and PPh3 in dioxane at 110 degreesC.
