This efficient reaction proceeds under very mild conditions with low cost nitration reagents and can be applied in gram-scale preparation.
A one‐pot diazotization/gold‐mediated cyclization of 2‐aminoaryl‐3‐arylpropargyl‐benzenesulfonamides is described. After diazotization, Me2SAuCl triggers an oxy‐ and/or chloroarylation of the alkyne moiety, resulting in the formation of 3‐acylindoles and/or
