An expedient method for the synthesis of fused glycosylquinolin-2-ones and glycosylspirooxindoles through an unprecedented intramolecularPd-catalyzed anomeric C–H activation of the sugar moiety of 2-bromophenyl glycosylcarboxamides is reported. The scope of the reaction is broad and tolerates a wide range of functional groups.
Palladium-Catalyzed Through-Space C(sp<sup>3</sup>)H and C(sp<sup>2</sup>)H Bond Activation by 1,4-Palladium Migration: Efficient Synthesis of [3,4]-Fused Oxindoles
Palladium two step: Linear anilides were converted into the title compounds in good to excellent yields through a palladium‐catalyzed domino carbopalladation/1,4‐palladium shift sequence. The C(sp3)‐Hactivation involves a seven‐membered palladacycle, and is chemoselective in the presence of competitive C(sp2)H bonds. DMA=N,N‐dimethylacetamide, OPiv=pivalate.
