    • note
    • 2O (4:1, v/v) solution (4 mL) of 2(G3) (0.01 mmol) were added olefin (1 mmol) and N-methylmorpholine N-oxide (NMO; 1.2 mmol) successively at room temperature under an argon atmosphere. After stirring the resulting mixture for 0.5-3 h, the dihydroxylation reaction was completed (monitored by TLC or GC). The reaction mixture was evaporated and dissolved in a small amount of acetone. The acetone solution was poured into 6 mL of water to precipitate 2(G3) as a grayish powder. After centrifugal separation, the aqueous solution was decanted, and the recovered 2(G3) was reused for subsequent dihydroxylation reactions.
