A bisphosphine/copper catalyst was used for the asymmetrichydroboration of 1,8‐naphthalenediaminatoboryl (Bdan) substituted alkenes (see scheme; pin=pinacolato). Simple alkyl‐substituted borylalkenes and styrene derivatives were hydroborated with high regio‐ and enantioselectivity. The electronic and steric properties of the Bdan group significantly affected the reactivity and regioselectivity of
