実験手順
2-Trimethylsilylethyl 2,3,6-tri-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl)-β-D-glucopyranoside (1) (Jansson et al., 1988) (29.4 g, 40 mmol) was stirred in methanolic sodium methoxide (5.8 mM, 515 mL) for 15 h. Neutralization with acetic acid, evaporation and crystallization from ethanol gave (2) (14.6 g, 82%).
