PROCEDURE
实验过程
A mixture of methyl 2-azido-4-O-biphenylcarbonyl-6-O-tert-butyldiphenylsilyl-2-deoxy-3-O-(4-methoxybenzyl)-1-thio-β-D-glucopyranoside (11) (150 mg, 0.19 mmol) and TEA (3 drops) in 1,3-propanedithiol (1 mL) was stirred at room temperature overnight. The reaction mixture was chromatographed using EtOAc—hexane 15:85 then EtOAc—hexane 1:1 solvent systems as mobile phases to give methyl 2-amino-4-O-biphenylcarbonyl-6-O-tert-butyldiphenylsilyl-2-deoxy-3-O-(4-methoxybenzyl)-1-thio-β-D-glucopyranoside (42) (130 mg, 91%).
