The Diastereoselective Alkylation of Arenesulfenate Anions Using Homochiral Electrophiles
摘要:
A series of Boc-protected beta-amino sulfoxides were prepared by the reaction of arenesulfenate anions with chiral Boc-protected beta-amino iodides. The stereoselective substitution reaction Is believed to arise through precoordination of the sulfenate counterion with the nitrogen lone pair of the electrophile.

The reaction of in situ generated arynes with aryl vinyl sulfoxides provides ortho-arylsulfinylaryl vinylethers via aryne σ-bond insertion into the S–O-bond and concomitant stereospecific S–O-vinyl migration. The cascade allows preparing di- or trisubstituted vinylethers with excellent stereospecificity. The reactions proceed under mild conditions, the substrate scope is broad, and the products obtained
