Gold(i)-catalyzed synthesis of 2-substituted indoles from 2-alkynylnitroarenes with diboron as reductant?

Abstract
An efficient method for the synthesis of 2-substituted indoles 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-substituted indoles with broad functional groups tolerance and excellent yields.
