homoallylic alcohols has been accomplished, which was catalyzed by a commercially available boronic acid. Due to the directing effect of the hydroxyl moiety, the ring opening reaction of a variety of 3,4-epoxy alcohols bearing different substitution patterns with various aromatic amines as nucleophiles proceeded in a stereospecific reaction pathway at the C-3 position furnishing various amino alcohols as products

Herein we report a bis-boric acid-mediated regioselective reductive aminolysis of 3,4-epoxy alcohols, providing new access to prepare amino diols in high diastereofidelity directly starting from nitroarenes. Notably, this step-economical process is enabled by the essential dual function of bis-boric acid, which is engaged initially in the 4,4′-bipyridine-catalyzed reduction of nitro compounds as the
