A cascade reaction giving nitromethyl-substituted oxindole derivatives was developed. The reaction used NaNO2 as the nitro source and potassium peroxydisulfate as an oxidant. This reaction proceeded via a radical mechanism involving substitution-desulfonlylation-cyclization steps in one pot and afforded good yields under mild conditions without using toxic metal catalysts. The resultant nitromethyl-substituted oxindole derivatives are convenient and valuable structures for different derivative syntheses.

Reaction of N-alkyl-N-arylsulfonyl-2-halo-propionamides with pentamethyldiethylenetriamine and either CuBr or CuCl leads to 2-aryl propionamides via initial radical generation, 1,4-aryl migration with loss of SO2 and reduction of the intermedia
