Arylboronic acids with the amino group in ortho position are widely used as carbohydrate receptors [1, 2]. They can be synthesized from o-formylphenylboronic acid by reduction of corresponding Schiff base:


An alternative method is the reaction of benzoxaborole I with amines:


Benzoxaborole I is a stable compound, easy to obtain from o-tolueneboronic acid by bromination and hydrolysis.

The spectroscopic characterization of the products II will be presented.
