With trifluoroacetic acid; In water; at 120℃; for 4h; | Compound 1 (about 4 mg) was added into a solution of water (1 mL) and 2N aqueous CF3COOH(2 mL), heated to 120°C under reflux conditions for 4 h. The mixture was diluted with water (2 mL) and then extracted with EtOAc (3 £2 mL). The combined organic phase was washed with brine and evaporated to dryness to afford the aglycones. The aqueous phase was concentrated. Then dry pyridine (1 mL) and L-cysteine methyl ester hydrochloride (2 mg) were added into the residue. Each mixture was reacted at 60°C for 1 h, and 0.5mL of (trimethylsilyl) imidazole dissolved in H2O was added, followed by heating to dryness at 60°C for 2 h. Each dried reactant was extracted with n-hexane (3 £ 1 mL) and H2O (1 mL, each). The n-hexane fraction was subjected to GC (column: Rtx-1, 0.25mm i.d. 0.25 mm, length 30 m). The conditions of GC were flame ionization detector; column temperature 100?180°C (10°C min?1)and 180?230°C (3°C min21); injector temperature 250°C; detector temperature 300°C and the carrier gas (N2, 0.8mLmin21). Under these conditions, these sugars of each reactants were identified by comparison with authentic samples: tR (min) 7.56 (D-ribose), 7.85 (L-ribose), 10.49 (D-glucose) and 11.10 (L-glucose). |
