Abstract:	A novel approach has been developed for the enantioselective synthesis of -chiral -acetoxyallylboronates via the copper(I)-catalyzed -boryl substitution of allyl acylals. This reaction proceeded with high E/Z selectivity and enantioselectivity (E/Z = >99:1, up to 80% yield, up to 99% ee). The subsequent allylation of aldehyde with the allylboronate afforded the monoprotected anti-1,2-diol derivative with high stereoselectivity.
