    • Replacing benzeneboronic acid with p-tolueneboronic acid (p-TBA) in Mohler and Czarnik's study, the complexation of alanine with p-TBA in DMSO provided up-field shifts of the aromatic protons from 7.67 (d, J = 7.3 Hz, 2H) and 7.13 (d, J = 7.3 Hz, 2H) to 7.32 (d, J = 8.0, 1H), 7.29 (d, J = 7.3 Hz, 1H) and 7.04 (v br d, 2H).
