An intermolecular hydroamination of allenamides with arylamines catalyzed by cationic Au(I) salts

An intermolecular hydroamination of allenamides with arylamines has been achieved under mild Au(I) catalysis conditions delivering allylamino E-enamides stereoselectively and in high yield. The reaction is made possible via a convenient method for conjugated N-acyliminium formation.
