A palladium-catalyzed chemo-, regio- and stereoselective coupling of oximes and alkoxy allenes enables the access to enantiomerically pure O,O-acetals, in which the hydrogen bonding interaction between the amide group of the diphosphine ligand and the alkoxy allene is decisive for the high enantioselectivity.
