In a series of transition metal-loaded CeO2 catalysts and Pt-loaded catalysts on various supports, Pt-loaded CeO2 shows the highest activity for the selectiveC-3alkylation of oxindole with octanol. The catalyst is effective for alkylation of oxindole and N-substituted oxindole with a series of substituted benzyl, linear, hetero-aryl alcohols under additive-free conditions and is recyclable.

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. This peroxidation

Alkylation with alcohols: Herein, nickel-catalyzed hydrogen borrowing strategy was employed for alkylation of 2-oxindoles using alkyl alcohols. Initial mechanisticstudies, deuterium labelling experiments and late stage synthetic modulation of the alkylated products were performed.
