Practically simple three-component chiral derivatisation protocols for determining the enantiopurity of vicinal C-2-symmetric diamines by H-1 NMR spectroscopic analysis are described. This involves the treatment of 1,2-diphenylethane-1,2-diamine or N-Boccyclohexane-1,2-diamine with 2-formylphenylboronic acid and enantiopure BINOL, which afford mixtures of diastereoisomeric boronate esters whose ratio is an accurate reflection of the enantiopurity of the parent diamine.
