An efficient method for Markownikoff's hydroamination-hydroarylation of alkynols using PtBr(2) as catalyst has been developed. The platinum-catalyzed reactions of alkynols with amino group containing aromatics were achieved in methanol over a reaction time of 6-24 h and temperature ranging from rt to 80 degrees C. This method works well for a variety of alkynols and aromatic amino compounds to give substituted pyrrolo[1,2-a]quinoxalines and indolo[3,2-c]quinolines in good to excellent yields.
