A number of functionalized β-amino and γ-amino sulfides and selenides have been synthesized involving a one-pot process of ring opening of cyclic sulfamidates with ‘in situ’ generated thiolate and selenoate species from diaryl disulfides and diphenyl diselenide using rongalite. A mild and efficient method has been developed for the synthesis of cysteines from serine.

the synthesis of beta-amino disulfides by regioselectiveringopening of sulfamidates with benzyltriethylammonium tetrathiomolybdate [BnNEt3](2)MoS4. Stability and reactivity of different protecting groups under the reaction conditions have been discussed. This methodology has also been extended to serine and threonine derived sulfamidates to furnish cystine and 3,3'-dimethyl cystine derivatives.
