Synthesis of Vinyl Sulfoxides and Subsequent Construction of C,S Contiguous Stereocenters Via Thia-Stevens Rearrangement of I III /S VI -Hybrid Ylides

-hybrid ylides into vinyl sulfoxides. Using Oppolzer's camphorsultam as a chiral auxiliary, a one-pot stereoselective [1,2]-thia-Stevens rearrangement/Michael addition cascade was further realized with a broad range of nucleophiles, delivering products bearing contiguous C,S-stereocenters.
