Palladium-Catalyzed Cross-Coupling Reactions of Electron-Deficient Alkenes with N-Tosylhydrazones: Functional-Group-Controlled CC Bond Construction

Palladium-Catalyzed Cross-Coupling Reactions of Electron-Deficient Alkenes with N-Tosylhydrazones: Functional-Group-Controlled CC Bond Construction

In the zone: A palladium‐catalyzed cross‐coupling reaction of electron‐deficient alkenes with N‐tosylhydrazones, which affords diverse CC bonds resulting from the functional‐group‐controlled effect, is reported (see scheme). These cascade transformations present remarkable stereoselectivity and a h...

Zusammenfassung:In the zone: A palladium‐catalyzed cross‐coupling reaction of electron‐deficient alkenes with N‐tosylhydrazones, which affords diverse CC bonds resulting from the functional‐group‐controlled effect, is reported (see scheme). These cascade transformations present remarkable stereoselectivity and a high synthetic potential. The presence of water substantially promotes both reaction routes.
