Herein, we report the first intramolecular C–N bond formation of phenylpropanamide derivatives via organocatalytic oxidative reactions, affording 3,3-disubstituted oxindole derivatives with up to 99% yield. The high efficiency of this reaction is exemplified by the transition metal-free mild conditions and the ability to perform the reaction on a gram scale. Meanwhile, the DFT calculation of the catalytic

The synthesis of a new polymer-supported coupling reagent derived from 1-hydroxybenzotriazole is described. An aminomethylated polystyrene was functionalized by reaction with 3-nitro-4-chlorobenzenesulfonyl chloride (2) followed by treatement with hydrazine hydrate, to give the polymeric N-benzyl-1-hydroxybenzotriazole-6-sulfonamide (4).The polymeric reagent 4 was shown to be highly efficient for the
