sp3-enriched secondary sulfonamides bearing an asymmetric center at the α position to the sulfur atom is described. The method relies on the electrophilic amination of the corresponding stereochemically pure sulfinates with N-alkylhydroxylamine sulfonic acids (in turn easily prepared from N-alkylhydroxylamine and HSO3Cl). It is shown that the efficiency of the approach is governed mainly by steric factors;
