This reagent is generated by treating 9-BBN with α-pinene. [2] This sterically crowded chiral trialkylborane can stereoselectively reduce aldehydes in what is known as the Midland Alpine borane reduction, or simply the Midland reduction. [3] C 8 H 12 B-pinanyl + RCDO → C 8 H 12 BOCHDR + (+)-d-pinene. Hydrolysis of the resulting borinic ester ...

The new reducing agent was later commercialized by Aldrich Co. under the name Alpine Borane and the asymmetric reduction of carbonyl groups with either enantiomer of Alpine-Borane is ...
