Abstract

Reaction of tetrahydrofolate model, 1-tosyl-3,4-dimethylimidazolinium iodide (1), and a series of aromatic or aliphatic amines produced N,N,N’-trisubstituted-2-methylethylenediamine derivatives (2-10) in good to excellent yields through a nucleophilic addition and the followed ring-opening mechanism. The coenzyme model was proved to be more electrophilic than those reported before.
