2 1. General Chemicals and solvents were purchased from commercial suppliers and used without further purification. TLC analysis was performed using pre-coated glass plates. Column chromatography was performed using silica gel ( mesh). IR spectra were recorded on a Perkin-Elmer PE-983 infrared spectrometer as KBr pellets with absorption in cm 1. 1 H NMR spectra were recorded on a Varian Mercury 400 or 600 MHz spectrometer Chemical shifts are reported in ppm, relative to the internal standard of tetramethylsilane (TMS). HRMS were obtained on an Apex-Ultra MS equipped with an electrospray source. Melting points were determined using XT-4 apparatus and not corrected. 2. Starting materials and other preparative substrates 2-bromobenzaldehydes (1a-lj), 2-iodobenzaldehyde (1k) and indolin-2-ones (2a-2h; 2r-2s) were commercially available, N-substituted indolin-2-ones (2i-2q) were prepared according to literature i as an example: A sealed vessel was charged with isatin (735 mg, 5 mmol), MeI (1065 mg, 7.5 mmol), K 2CO 3 (1.38g, 10 mmol) at room temperature, and then solvent DMF (20 ml) was added. The resulting mixture was stirred at 80 C in a sealed vessel under Ar atmosphere, after disappearance of the reactant (monitored by TLC), then added 50 ml water to the mixture, extracted with EtOAc 3 times (3 50 ml). The extract was washed with 30% NaCl solution (V/V), dried over anhydrous Na 2SO 4 and concentrated under reduced pressure. The residue was next dissolved to 30 ml EtOH, hydrazine hydrate (85%, 10 ml) under Ar was added. The mixture was stirred at 90 o C for 24 h. After cooling to room temperature, the solution was concentrated. The residue was diluted with H 2O, and the resulting solution was extracted with EtOAc. The combined organic phases were washed with 30% NaCl solution, dried with Na 2SO 4, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate) to provide 1-methylindolin-2-one 2i as a dark yellow solid. Compounds 4 were prepared according to literature. -S2-
3 To a solution of 2-oxindole (1.33 g, 10 mmol) in methanol was added 2-bromobenzaldehyde (1.85 g, 10 mmol) and catalytic amount of piperidine (85mg, 1mmol). The mixture was heated in 30mL EtOH to reflux for 3 hours and cooled to room temperature, then the solid were filtered and recrystalization from ethanol to afford (E)-3-(2-bromobenzylidene)indolin-2-one (4) as a yellow solid. Compound 6 were prepared according to literature (Cholakova, T.; Vasilev, A.; Ninjo, N.; Dobrev, A. Heterocycl Commun. 2005, 11,181.). 3.

General procedure for preparation of 3aa-3ah, 3ai-3aq (3aa as an example) General procedure: A sealed tube was charged with 2-bromobenzaldehyde 1a (93 mg, 0.5 mmol), indolin-2-one 2a (106 mg, 0.8 mmol), Cs 2CO 3 (489 mg, 1.5 mmol) at room -S3-
4 temperature, and then dried solvent DMSO (4 ml) was added. The resulting mixture was stirred at 120 C in a sealed vessel under Ar atmosphere, after disappearance of the reactant (monitored by TLC), then added 50mL water to the mixture, extracted with EtOAc 3 times (3 50 ml). The extract was washed with 30% NaCl solution (V/V), dried over anhydrous Na 2SO 4 and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (Petroleum ether / ethyl acetate = 2:1) to yield the desired product 3aa as a yellow solid (85% yield). 5.

8 6. Additional control experiments and further discussion of the reaction mechanism (1) Other organic additives with methylene were tested under the standard conditions, and all cases were shown in the table below. (2) Mixtures of products were formed when different N-substituted indolin-2-ones (2i or 2c) were used as additives. A possible dynamic equilibrium between 4, 5, 5, and 4 was proposed to explain these results from the control experiments in Scheme 4 (4 + 2i as example), and additional control experiment suggest that 5, 5 was also possible cyclization precursor. (3) A phenyl radical-induced aromatic 1,6-hydrogen transfer might invloved in the mechanism (R = H; 3 = 3 ). Two regioisomers would be obtained when 5-substituted 2-bromoaldehyde were used as substrates (R H; 3 3 ). -S8-
9 (4) The mechanism involving Michael addition of enolates A to 4 followed by intermolecular electron transfer is also possible, in other words, 6 was also possible cyclization precursor. Initially, deprotonation of the CH 2 protons within indolin-2-one (2a) generates the eletron-rich enolate anion (A) in the presence of Cs 2CO 3. Most of enolate anion (A) condenses with 2-bromobenzaldehyde, leading to the formation of 4, followed by Michael addition of enolates A to 4. The resulting intermediate 6 would undergo base-promoted homolytic aromatic substitution with the assistance of electrons released from the rest of enolates. -S9-
