Nickel-catalyzed reductive cross-coupling (RCC) reactions between alkenes and alkyl electrophiles are undoub- tedly the attractive approaches to new functionalized heterocycles. However, the alkylation reagents are still rather limited for the arylalkylation of tethered alkenes via RCC reactions. Thus, developing more robust methods to access heterocycles from stable and readily available starting materials under RCC conditions is still highly challenging and desirable. A new nickel- catalyzed reductive arylalkylation of tethered alkenes with cyclosulfonium salts as C(sp3) electrophiles to access the sulfur- containing oxindoles is developed. This tandem ring-opening/cyclization/reductive coupling protocol enables the efficient construction of various oxindoles bearing all-carbon quaternary centers under mild conditions with broad functional group tolerance. Notably, many drug derivatives are readily functionalized using the developed protocol.
