ChemInform Abstract: Nickel‐Catalyzed Diastereoselective Reductive Coupling Reaction of Norbornene with Aldehydes in the Presence of Triethylborane.

Abstract Aliphatic and aromatic aldehydes (II) and (V) undergo a reductive coupling reaction with norbornene (I) and norbornadiene (IV) in the presence of triethylborane as reducing agent and a Ni—phosphine catalytic system to provide the secondary alcohols (III) and (VI), resp., in a smooth and highly diastereoselective fashion.
