実験手順

A mixture of D-mannosamine hydrochloride (863 mg, 4.0 mmol), N-succinimidyl 4-pentynoate 9 (781 mg, 4.0 mmol), triethylamine (1.67 ml, 12.0 mmol) in DMF (31 ml) was stirred at room temperature overnight. The reaction mixture was concentrated in vacuo, and the residue was purified by flash column chromatography (CHCl3/MeOH 8:1) to give N-4-Pentynoylmannosamine, 10 (898 mg, 87%); 1H-NMR (500 MHz, D2O) 2.37 (t, 2.63H, J=2.5 Hz), 2.48-2.63 (m, 10.5H), 3.38-3.42 (m, 1H), 3.52 (t, 1H, J=10 Hz), 3.63 (t, 1.63H, J=10 Hz), 3.69-3.91 (m, 7.89H), 4.05 (dd, 1.63H, J=4.5 and 10 Hz), 4.35 (dd, 1.63H, J=1.5 and 4.5 Hz), 4.47 (dd, 1H, J=1.5 and 4.5 Hz), 5.03 (d, 1H, J=1.5 Hz), 5.13 (d, 1.63H, J=1.5 Hz); 13C-NMR (125 MHz, D2O)□ 14.78, 14.91, 34.62, 34.79, 53.67, 54.50, 60.91, 60.93, 67.01, 67.28, 69.25, 70.56, 70.71, 72.47, 72.50, 76.80, 84.04, 84.45, 93.36, 93.67, 175.68, 176.41; ESI-TOF-HRMS m/e calculated for (M+H)+ C11H17NO6260.1129; found 260.1120.
