Decarboxylative allylation of glycals: A β-type glycosidic bond has been constructed in high regio- and stereoselectivity by means of a palladium-catalyzed decarboxylative O-glycosylation. Various kinds of glycals with different protecting groups have been examined for this reaction to afford a diverse set of glycosylated products, including phenolic O-glycosides, thiophenolic S-glycoside, aliphatic O-glycosides, and disaccharides with excellent β-selectivity and reasonable to excellent yields.
通过钯催化的脱羧O-糖基化反应，以高区域选择性和立体选择性构建了β-型糖苷键。已对各种带有不同保护基的糖烯进行了该反应研究，以得到一系列多样化的糖基化产物，包括酚类O-糖苷、硫酚类S-糖苷、脂肪族O-糖苷以及具有优异β-选择性和良好至优异产率的二糖。
