Abstract During the preparation of 3- C -(6- O -acetyl-2,3,4-tri- O -benzyl-α- d -mannopyranosyl)-1-propene, using a published Sakurai-type reaction on the parent methyl glycoside, some observations were made on the sensitivity to reaction conditions that were not previously reported. This Note presents the study of this allylation reaction followed by acetolysis, which ultimately led to the best conditions
摘要在已公开的樱井型母体甲基上,制备3-C-(6-O-乙酰基-2,3,4-三-O-苄基-α-d-甘露吡喃糖基)-1-丙烯对于糖苷,对反应条件的敏感性进行了一些观察,以前没有报道过。本说明介绍了此烯丙基化反应及其后进行乙酰分解的研究,最终导致了获得C-糖苷的最佳条件,并进行了进一步转化以生成相应的醛和酸性衍生物。
