Catalytic hydrogenation of aldose oximes affords bis(polyhydroxyalkyl)amines. These compounds and their N-carboxymethyl derivatives react with borate ions to give macrocyclic diborate diesters. The presence of an N-carboxymethyl group raises the capacities for the sequestration of Ca2+, Cu2+, and Cd2+. The N-carboxymethyl derivatives possess strong affinity for Ca2+ (pH > 11) and Cd2+ both in the absence and presence of borate.
