A highly efficient one-pot synthesis of chiral α-allenols from propargylic alcohols, aldehydes and pyrrolidine induced by CuBr and (R,R_a)-N-PINAP or (R,S_a)-N-PINAP and CdI₂ has been developed. Both the yields and enantioselectivities of the allenols of this one-pot procedure are practical. Comparison with ZnI₂ control experiments revealed that CdI₂ can convert propargylic amine to allene in the presence of CuBr efficiently.
