A Rh-catalyzed hydroboration of α, β-unsaturated carbonyl compounds with pinacolborane proceeds with high levels of regio-, diastereo-, and enantioselectivities to provide products with two vicinal stereocenters. Through the appropriate choice of substrate geometry (E or Z) and ligand enantiomer, all possible diastereoisomers are readily accessible.
