Enantioselective hydroboration of ketones and imines provides a powerful method to access valuable chiral alcohols and amines which are widely used in organic synthesis, materials science, pharmaceutical, agrochemistry and fine chemical industry. After invented in 1991, pinacolborane (HBpin) as a stable, commercially available and measurably simple reductive reagent has been widely applied in hydroboration of carbonyl derivatives, imines and nitriles and relevant mechanistic investigation. In the past 5 years, HBpin has also been employed for asymmetric catalytic hydroboration (CHB) to access chiral alcohols and amines. The enantioselective CHB reactions of ketones and imines using HBpin are outlined according to the classification of different catalysts, such as earth abundant transition metals, main group elements, and rare-earth metals.

Key words: pinacolborane, asymmetric hydroboration, earth abundant transition metal, ketone, imine
