通过在乙腈中使用氰化汞,将 2,3,4,6-四-O-乙酰基-α-D-吡喃葡萄糖基溴与甲基 2,3-O-异亚丙基-α-L-吡喃鼠李糖苷缩合(Helferich 反应),合成了 4-O-(β-D-吡喃葡萄糖基)-L-鼠李糖(苏打二糖),收率 55%。二糖和衍生的糖醇都是糖浆,但各自形成结晶全乙酸酯。描述了 1-脱氧-D-赤藓糖醇的便捷合成。
4-O-(β-D-Glucopyranosyl)-L-rhamnose (scillabiose) has been synthesized in 55% yield by condensation of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide with methyl 2,3-O-isopropylidene-α-L-rhamnopyranoside using mercuric cyanide in acetonitrile (Helferich reaction). The disaccharide and the derived alditol are both syrups but each forms a crystalline peracetate. A convenient synthesis of 1-deoxy-D-erythritol is described.
