During a synthetic study targeting 3,5-dithio-glucofuranose, two interesting intramolecular displacement reactions that both generated the 3,6-thiaanhydro structures were discovered. We successfully solved the intramolecular displacement problem by using a 5-S,6-O-isopropylidene protecting group and synthesized the 3,5-dithio-glucofuranose in overall 9 % yields after 14 steps.
在一项针对 3,5-二硫代呋喃葡萄糖的合成研究中,发现了两个有趣的分子内置换反应,它们都产生了 3,6-硫杂酐结构。我们通过使用 5-S,6-O-异亚丙基保护基成功地解决了分子内置换问题,并在 14 步后以 9% 的总产率合成了 3,5-二硫代呋喃糖。
