with aliphatic peroxide was developed under mild conditions. A library of linear alkylated and arylated peroxides are synthesized in good to excellent yield. This method is highly selective and general for a range of biologically important derivatives of 2-oxindole, barbituric acid, and 4-hydroxy coumarin with a good functional group tolerance and without the cleavage of the peroxide bond.

quantitative yields and high enantiomeric purity (89–95% ee) were attained in the course of 100 reaction cycles of a polystyrene resin-supported Cinchonaalkaloidorganocatalyst in the enantioselective α-amination of 2-oxindoles with diethyl azodicarboxylate. The catalytic material proved stable for >5300 h operation time over 8 months.
