Chiral α-allenols are prepared with high diastereocontrol through an unprecedented and spontaneous β-oxygen elimination of an α-epoxy vinyl boronate. Stochiometric experiments and DFT calculations support a dual role of the copper catalyst, which orchestrates the hydroboration and the syn-elimination step.

Transmetallation of (E)-1-phenyl-3-(tributylstannyl)propene and 3-phenyl-3-(tributylstannyl)propene with BuSnCl3, and the isomerization of the transmetallated product are described.The application of the reactions to stereoselective (Z)-3-phenyl-2-propenylation and threo-1-phenyl-2-propenylation of aldehydes is also described.
