synthetized using phase-transfer catalyzed reactions from per-O-acetylated lactosyl bromide. The aldehyde group of the vanillin moiety was then modified to generate a series of related analogs having variable functionalities in the para- position of the aromatic residue. The corresponding unprotected lactosides, obtained by Zemplén transesterification, were regioselectively 3′-O-sulfated using tin chemistry
使用相转移催化反应从全-O-乙酰化乳糖基溴合成基于香草醛的乳糖苷衍生物。然后对香草醛部分的醛基进行修饰,生成一系列在芳香族残基的对位具有可变官能团的相关类似物。通过 Zemplén 酯交换反应获得的相应未保护乳糖苷,使用锡化学活化进行区域选择性 3'-O-硫酸化,然后用三氧化硫-三甲胺复合物 (Men3N-SO3) 处理。还使用 Knoevenagel 反应从香兰素醛制备其他衍生物,以提供延伸的 α,β-不饱和羧酸,然后将其还原为饱和对应物。
