WebThe copper-catalyzed diboration of aldehydes was used in conjunction with the Matteson homologation, providing the efficient synthesis of β-hydroxyboronate esters. The oxygen-bound boronate ester was found to play a key role in mediating the homologation reaction, which was compared to the α-hydroxyboronate ester (isolated hydrolysis product).

Diisopinocampheylborane was originally prepared by hydroboration of excess α-pinene with borane, but it is now more commonly generated from borane-methyl sulfide (BMS). The compound can be isolated as a solid. However, because it is quite sensitive to water and air, this reagent is often generated in situ and used as a solution. Diisopinocampheylborane is monomeric, in contrast to diborane and many of its less bulky anal…
