A facile and economic method for the fully regioselective and high-yielding protocol for the hydroamination of unsymmetrical internal alkynes under mild reaction conditions with AgNTf2 was developed. The materials are easily available from commercial vendors, to give synthetically useful enamine derivatives efficiently. This strategy is efficient to build complex structures from simple starting materials in an environmentally compatible fashion.
