acyclic aminodienes catalyzed by Lewis acids such as silver triflate, cationicgoldcomplexes, BINAP―copper(II) triflate, iron trichloride, indium(III) bromide, iodine and by TfOH, as a representative Bronsted acid, are evaluated. The reaction proceeds in a 1,4-addition manner through a 5-exo-trig cyclization affording the corresponding 2-substituted pyrrolidines, (triphenylphosphite)gold(I) triflate, and
