Synthesis of 3,3-disubstituted oxindoles by visible-light-mediated radical reactions of aryl diazonium salts with N-arylacrylamides

A mild and efficient visible-light-mediated diarylation of N-arylacrylamides with aryl diazonium salts under mild conditions has been developed. This method provides convenient access to a variety of useful 3,3-disubstituted oxindoles by constructing two C-C bonds in one step.

LCopper-catalyzed diarylation of activated alkenes with diaryliodonium salts

Cu(OTf)2-catalyzed diarylation of activated alkenes by using diaryliodonium(III) salts has been developed. With this method, arylated oxindoles can be easily accessed in good yields. Insights into the mechanism of copper-catalyzed arylations are discussed, and the findings are expected to help increase the level of understanding of catalytic arylations with diaryliodonium salts.

Copper(I)-catalyzed aryl or vinyl addition to electron-deficient alkenes cascaded by cationic cyclization

An exoselective copper-catalyzed arylation- and vinylation-carbocyclization of electron-deficient alkenes was developed to provide rapid and efficient access to a variety of functionalized 3,3-disubstituted oxindoles. With this method, a highly efficient and concise formal synthesis of (±)- physostigmine and (±)-physovenine has been completed.

Copper-catalyzed oxidative electrophilic carbofunctionalization of acrylamides for the synthesis of oxindoles

A novel and efficient copper-catalyzed tandem oxidative cyclization of arylacrylamides with diaryliodonium salts is reported. This reaction provides a novel approach for the synthesis of oxindoles and various functional groups were well tolerated.

Copper-catalyzed bis-arylations of alkenes leading to oxindole derivatives

A simple and practical copper-catalyzed approach to oxindole derivatives by copper-catalyzed bis-arylation of N-alkyl-N-phenylacrylamides with diaryliodonium triflates has been developed under mild conditions, and the method is of tolerance towards some functional groups in the substrates.

Asymmetric synthesis of oxindoles containing a quaternary stereogenic centre by catalytic O/C-carboxyl rearrangement

A catalysed O/C-carboxyl rearrangement generates the all-carbon stereogenic centre in phenyl 1,3-dimethyl-5-methoxy-2-oxoindoline-3-carboxylate (up to 57% ee). Crystallisation and removal of racemic crystals enhance the ee to 95%. The X-ray crystal struct
