General description

The 3-nitro-2-pyridinesulphenyl (Npys) moiety is useful as a protecting-activating group for cysteine, particularly in the synthesis of cyclic and unsymmetrical disulfides.[1] The stability of NpysCl was studied in various solvents.[2]

Application

3-Nitro-2-pyridinesulfenyl chloride (NpysCl) was employed as the starting material for the synthesis of N-, O- and S-Npys-protected amino acid.[2]
