The reaction of 2-(3-methoxypyridyl) β-d-gluco- and d-galactopyranosides with various carboxylic acids affords the corresponding α-1-esters in high yields. Aspirin can be solubilized in water as the α-d-galactopyranosyl ester.
2-(3-甲氧基吡啶基)的β-D-葡萄糖苷和D-半乳糖苷与多种羧酸反应,以高产率生成相应的α-1-酯。阿司匹林可以作为α-D-半乳糖苷酯在水中的可溶形式存在。
