Salicylidene hydrazides represent important ligands forming oxovanadium complexes. Carbohydrate-derived chiral salicylidene hydrazides as ligands for metal ion complexation were synthesized for the first time. The pathway of the mild and selective synthesis starts from commercial saccharides like methyl-α-d-glucopyranoside and methyl-α-d-mannopyranoside. All synthesized carbohydrate-derived salicylidene hydrazides are able to form oxovanadium complexes. The mononuclear structure proposed for the complex of 1,2,3,4-tetra-O-methyl-α-d-glucopyranuronic acid salicylidene hydrazide is consistent with the analytical data (NMR, IR and MS).
