Zn(II)/Cu(I)-mediated asymmetric synthesis of simple axiallychiral allenes from terminal alkynes and aldehydes was realized by taking advantage of the chiral amine (S)-α,α-diphenylprolinol 3. This one-pot procedure is compatible with broad scopes of both terminal alkynes and aldehydes, providing axiallychiral allenes in practical yields with an excellent enantioselectivity. Control experiments revealed that CuBr
