I. General procedures

All reagents and solvents were purchased from commercial sources and used without further purification unless otherwise stated. All reactions were monitored by thin-layer chromatography (TLC). All reactions were carried out in argon atmosphere unless otherwise stated. Column chromatography was performed on silica gel (200-300 mesh) and visualized with ultraviolet light. Ethyl acetate and petroleum ether were used as eluents. 1H, 13C and 19F spectra were recorded at room temperature on a Varian Mercury plus 300 or Bruker AV400 or Agilent INOVA 600 MHz with TMS as an internal standard and CDCl3 as solvent. Fourier transform infrared spectra (FT-IR) were recorded on Agilent Technologies Cary 630 instrument or Bruker TENSOR 27 instrument. HRMS analyses were made by Lanzhou University by means of ESI. Melting points were measured on micro melting point apparatus and uncorrected.

II. General procedures for preparation of starting materials

i. General procedures for preparation of starting materials 1a~1f, 1h~1i, 1m~1w

Starting materials 1a~1f, 1h~1i, 1m~1z were synthesized according to the literature procedures[1]. Salicylaldehyde (1.17 g, 9.6 mmol, 1.2 equiv.), 2-bromopyridine (1.26 g, 8.0 mmol, 1.0 equiv.), CuI (76.2 mg, 0.4 mmol, 0.05 equiv.), picolinic acid (98.5 mg, 0.8 mmol, 0.1 equiv.) and K3PO4 (3.4 g, 16 mmol, 2.0 equiv.) in 16 mL dry DMSO were heated at 80 °C for 24 h under argon. The reaction mixture was cooled to room temperature, 16 mL H2O was added and extracted with 3 × 50 mL EtOAc. The combined organic phases were washed with brine, dried over anhydrous

MgSO4 and concentrated under reduced pressure. Purification by column chromatography on silica (PE/EA = 16/1) affords 1a.

ii. General procedures for preparation of starting materials 1j~1l and 1x~y

Starting materials 1j~1l and 1x~y were synthesized according to the literature procedures[2]. Salicylaldehyde (977 mg, 8.0 mmol, 1.0 equiv.), 2-chloro-5-(trifluoromethyl) pyridine (1.45 g, 8.0 mmol, 1.0 equiv.) and K2CO3 (1.11 g, 8.0 mmol, 1.0 equiv.) in 16 mL dry DMF were heated at 150 °C for 5 h under argon. The reaction mixture was cooled to room temperature, 16 mL H2O was added and extracted with 3 × 40 mL EtOAc. The combined organic phases were washed with brine, dried over anhydrous MgSO4 and concentrated under reduced pressure. Purification by column chromatography on silica (PE/EA = 25/1) affords 1j.

iii. General procedures for preparation of starting material 1g

Starting material 1g was synthesized according to the literature procedures[1]. 2-Bromobenzaldehyde (1.78 g, 9.6 mmol, 1.2 equiv.), 5-fluoropyridin-2-ol (0.9 g, 8.0 mmol, 1.0 equiv.), CuI (76.2 mg, 0.4 mmol, 0.05 equiv.), picolinic acid (98.5 mg, 0.8 mmol, 0.1 equiv.) and K3PO4 (3.4 g, 16 mmol, 2.0 equiv.) in 16 mL dry DMSO were heated at 80 °C for 24 h under argon. The reaction mixture was cooled to room temperature, 16 mL H2O was added and extracted with 3 × 50 mL EtOAc. The combined organic phases were washed with brine, dried over anhydrous MgSO4 and concentrated under reduced pressure. Purification by column chromatography on silica (PE/EA = 20/1) affords 1g.

iv. General procedures for preparation of starting materials 1z~1ag

Starting materials 1z~1ag were synthesized according to the literature procedures[2]. To a DMA (16 mL) solution containing 2-fluorobenzaldehydes (0.85 mL, 8.0 mmol, 1.0 equiv.) and 4-hydroxybenzonitrile (954 mg, 8.0 mmol, 1.0 equiv.) were added K2CO3 (1.10 g, 8.0 mmol, 1.0 equiv.), and the reaction mixture was stirred for 3

h at 170 °C under argon atmosphere. The reaction mixture was cooled to room

temperature, diluted with H2O (16 mL), extracted with EtOAc (40 mL x 3), and the

organic layer was washed with brine, dried with anhydrous MgSO4 and concentrated under reduced pressure. Purification by column chromatography on silica (PE/EA = 25/1) affords 1z.

V. General procedures for heteroaryl/aryl rearrangement

i. General procedures for heteroaryl rearrangement

The starting materials 1 (0.2 mmol), TFA (0.2 mmol) were added into 2.0 mL of ethyl acetate in an airtight quartz tube, which was then evacuated by four freeze-pump-thaw cycles and back-filled with ultra-purified argon prior to use. The reaction was stirred at room temperature under UV irradiation (254 nm) for 24 h and 5 mL saturated NaHCO3 aqueous solution was added into the reaction solution, and extracted with 3 × 5 mL EtOAc. The combined organic phases were washed with brine, dried over anhydrous MgSO4 and concentrated under reduced pressure. Purification by column chromatography on silica (PE/EA = 20/1) affords 2.

The reaction was stirred at room temperature under UV irradiation (254 nm) for 24 h. The reaction mixture was concentrated under reduced pressure.
