The palladium catalyzed allyl-allyl cross-coupling was investigated with substituted prochiral allylic boronates. These reactions deliver products bearing adjacent stereocenters and the issue of diastereocontrol is therefore paramount. Under appropriately modified conditions, this allyl-allyl coupling strategy was found to apply to a range of substrates, generally occurring with high enantioselectivity (92:8 – >99:1 er) and good diastereoselection (4:1 – 14:1 dr).
