Monodeoxy derivatives of 2-(trimethylsilyl)ethyl (Me3SiEt) beta-lactoside were synthesized, by deoxygenation at the disaccharide level, for the 2'-, 3'-, 4'-, and 6'-monodeoxylactosides. The 2-, 3-, and 6-deoxy derivatives were synthesized by beta-D-galactosylation of suitably protected monodeoxygenated Me3SiEt glucosides. Silver silicate was shown to be an efficient glycosylation promoter in the preparation
通过在二糖水平上脱氧,合成2-(三甲基甲硅烷基)乙基(Me 3 SiEt)β-乳糖苷的单脱氧衍生物,用于2'-,3'-,4'-和6'-单脱氧乳糖苷。通过适当保护的单脱氧Me3SiEt葡糖苷的β-D-半乳糖基化合成2-,3-和6-脱氧衍生物。在制备2-和3-脱氧乳糖苷中,硅酸银被证明是有效的糖基化促进剂。
