• Reagent for protection of amino groups as benzylsulfonamides which can be cleaved reductively, e.g. Na/NH3, Raney Ni/H2: J. Am. Chem. Soc., 79, 639, 645 (1957), or by photolysis: Tetrahedron Lett., 1029 (1979).
• Alcohols can also be protected, e.g. in the presence of 2,6-lutidine, as benzylsulfonates which can be cleaved with NaNH2 in DMF: Bull. Chem. Soc. Jpn., 59, 1587 (1986).
