A new application of the formazyl activation provided selectively protected new derivatives of both 2-deoxy-D-galactose and 2-acetamido-2-deoxy-D-galactose formazans from 6-amino-6-deoxy-D-galactose 6,4-cyclic carbamate (1) under very simple conditions. The 1 H NMR spectrum of the acetylated 2-deoxy derivative 7 revealed an equilibrium between chelated and unusual non-chelated forms of the formazan moiety in solution.
