Intermolecular Regio- and Stereoselective Sulfenoamination of Alkenes with Thioimidazoles.

An intermolecular sulfenoamination reaction utilizing a stable sulfur precursor with a broad range of alkene structures is described. More importantly, these reactions proceed in a highly regio- and stereoselective manner to afford interesting heterocyclic motifs ready for biological studies. In addition, a highly regiodivergent approach to access the opposite regioisomers for styrene derivatives was also developed.
