  An easy to operate method of catalytic hydroboration of unsaturated compounds has been developed with wide substrate scope. Reactions of various aldimines, ketimines, α,β-unsaturated carbonyl compounds, and alkynes were successfully executed with bis(pinacolato)diboron and N-heterocyclic carbenes in methanol without requiring a transition metal or inert atmosphere.

  A general and efficient new method for the asymmetric synthesis of a-amino boronate esters has been developed. The key step is the Cu(I)-catalyzed addition of bis(pinacolato)diboron to N-tert-butanesulfinyl aldimines, which proceeds in good yields (52-88%) and with very high diastereoselectivities (>96:2) for a variety of aldimine substrates. This method was applied to an efficient synthesis of bortezomib, a potent a-amino boronic acid inhibitor of the proteasome that is in clinical use for the treatment of multiple myeloma and mantle cell lymphoma.

  By using a benzimidazole core and N-substitutions to tune the electronic properties of the corresponding N-heterocyclic carbenes, a one-pot protocol for efficient synthesis of alpha-aminoboronic esters without the need of a glovebox was developed in this work. The starting materials for the transformation can also be extended from aldehydes to ketones. An alternative protocol with short reaction time using preformed carbene-copper chloride is also described.
