AbstractUvacalols are novel carbasugars isolated from the genera Uvaria. In this study, we report concise syntheses of (1R,2S,3R,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol, a key intermediate for the synthesis of uvacalols I and J, and of its epimer (1R,2S,3S,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol, starting from cheap and readily available methyl d-glucopyranoside.
摘要Uvacalols是从Uvaria属中分离出来的新型carbasugars。在这项研究中,我们报告了 (1R,2S,3R,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol 的简明合成,它是合成 uvacalols 的关键中间体I 和 J,及其差向异构体 (1R,2S,3S,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol,从廉价且容易获得的甲基 d-吡喃葡萄糖苷。
