    • 4 (0.1 mmol, 16 mg) were placed in an oven-dried round-bottomed flask. Subsequently methanol (3 mL) and boronic acids (1.0 mmol) were added. The reaction mixture was stirred vigorously at room temperature for a certain time (monitored by TLC analysis). The resulting mixture was concentrated in vacuo, and the residue was extracted with petroleum ether or purified by a pad of silicon gel to give the desired aryl or vinyl azide.

    • 4 (0.1 mmol, 16 mg), and boronic acids (1.0 mmol) were reacted in methanol (3 mL) as described above for 5-14 h. Then water (3 mL), sodium ascorbate (0.5 mmol), and phenylacetylene (1.1 mmol) were added into the reaction mixture. The resulting mixture was stirred vigorously at room temperature for 2-4 h (as monitored by TLC analysis). Some precipitate was formed and collected by a simple filtration. After the precipitate was washed with water (3 × 25 mL), it was dried in air or further purified by flash chromatography to afford the pure product.
