With the aim of developing easily accessible chiral Lewis acids for asymmetrichydrogenation, a variety of binaphthyl-based chiral alkenes were prepared in one step from the corresponding diols. Using the in situ generated chiral boron Lewis acids through the hydroboration of chiral alkenes with Piers’ borane, metal-free asymmetrichydrogenations of imines were realized to furnish the desired amine
