report a synthesis of Levuglandin E2, as a mixture of easily separable diastereomers (15‐E2‐isoketals). The key feature is the protection of its reactive aldehyde as dimethyl acetal, which is introduced with 2,2‐dimethoxyethanal and removed in minutes with Montmorillonite K‐10. The synthesis could be modified to the preparation of 15‐E2‐isoketals with stable isotopes or with radiolabels.
摘要 我们报告了 Levuglandin E2 的合成,作为易于分离的非对映异构体 (15-E2-isoketals) 的混合物。关键特征是将其反应性醛保护为二甲基乙缩醛,通过 2,2-二甲氧基乙醛引入,并在几分钟内用蒙脱石 K-10 去除。合成可以修改为具有稳定同位素或放射性标记的 15-E2-isoketals 的制备。
