Building from a previous communication, the reaction of sulfenate anions with chiral N-Boc-protected β-substituted β-amino iodides was evaluated as a conceptually different synthetic approach to chiral β-substituted β-amino sulfoxides. Using arenesulfenat

(Chemical Equation Presented) A general, efficient, and experimentally simple method for the generation of sulfenate salts has been developed using β-sulfmylesters as substrates. The process is based on a retro-Michael reaction, initiated by deprotonation at low temperature. Upon treatment with alkyl halides, the liberated sulfenates are subsequently converted into sulfoxides in good to excellent yield. Extension of the methodology to an unprecedented access to nonracemic sulfoxides by introduction of an enantiopure ligand, (-)-sparteine, is also described.
