A novel palladium‐catalyzed [4+1] spiroannulation was developed by using a C(sp3)−H activation/naphthol dearomatization approach. This bimolecular domino reaction of two aryl halides was realized through a sequence of cyclometallation‐facilitated C(sp3)−H activation, biaryl cross‐coupling, and naphthol dearomatization, thus rendering the rapid assembly of a new class of spirocyclic molecules in good...
An efficient one‐pot assembly of all‐carbon spiro‐oxindole compounds from non‐oxindole‐based materials has been developed through a palladium‐catalyzed asymmetric Heck/carbonylative lactonization and lactamization sequence. Diversified spirooxindole γ‐and δ‐lactones/lactams were accessed in high yields with good to excellent enantioselectivities (up to 99 % ee) under mild reaction conditions. The...
