The hydroamination of allenes proceeded smoothly in the presence of gold catalysts to give the corresponding 2-vinyl pyrrolidines and piperidines in high yields. The reaction is very efficient and can be carried out with only 1–5 mol % catalyst at room temperature and under extremely mild conditions. As an example of chirality transfer, it is shown that aminoallene 1a (96% ee), synthesized from (S)-(−)-1-octyn-3-ol
