This short review summarizes our laboratory’s development of benzylboronic esters
as nucleophiles. Activation of the benzylboronic ester is achieved by irreversible
coordination of an alkyllithium Lewis base to form a nucleophilic benzylboronate.
This boronate was found to react with aldehydes, imines, ketones, and alkyl bromides.
A copper catalyst was employed in reactions of the boronate with epoxides and aziridines.
Key words
boron - benzylation - Lewis base - copper - boronate
