A metal-free oxidative tandem coupling of activatedalkenes with carbonyl C(sp2)–H bonds and arylC(sp2)–H bonds using TBHP is established for the synthesis of 3-(2-oxoethyl)indolin-2-ones. This method allows 1,2-difunctionalization of the C–C double bond in N-arylacrylamides by simultaneous formation of two C(sp2)–C(sp3) bonds.

natural products. A new oxidativetandem route to the assembly of 3-(2-oxoethyl)indolin-2-ones from N-arylacrylamides and alcohols has been established by using inexpensive and environmentally benign iron catalysts and peroxides. In the presence of Fe(OAc)2 and tert-butyl hydroperoxide, a variety of arylacrylamides underwent the oxidative 1,2-carboacylation reaction with alcohols to give the corresponding
