Anionic Cross-Coupling Reaction of α-Metallated Alkenyl Sulfoximines and Alkenyl Sulfoximines with Cuprates Featuring a 1,2-Metal-Ate Rearrangement of Sulfoximine-Substituted Higher Order Alkenyl Cuprates and an α-Metallation of Alkenyl Sulfoximines by Cu

nucleofuge. The parent (E)- and (Z)-configured alkenyl sulfoximines suffer upon treatment with an organocuprate a deprotonation at the alpha-position with formation of the corresponding alpha-cuprioalkenyl sulfoximines. These derivatives also enter into a similar ACCR with organocuprates. The ACCR of sulfoximines substituted homoallylic alcohols allows a stereoselectiveaccess to enantio- and diastereopure
