Transition-metal-catalyzed C-H functionalization has been extensively investigated with great application in the syntheses of bioactive molecule and functional materials.1Meanwhile,catalytic C-C bond-cleavage reactions have also emerged as powerful approaches to quickly build molecules with high complexity.2 In our work,an efficient rhodium(Ⅲ)-catalyzed C7 allylation of indolines with VCPs.This strategy provides a simple and practical route to access indoline derivatives via sequential C-H and C-C activation,which is featured with broad substrate scope,good functional group compatibility,and high regio-and diastereoselectivities.The obtained allylated indolines could be further utilized as synthetic precursors via late-stage diversification.This reaction represents a new methodology to functionalize indolines by emerging C-H and C-C cleavage into a single step.
