s and preliminary exploration of their synthetic potential. Prolonged epoxidation reaction times led to their hydrolysis in situ and gave novel protected D-hexos-5-ulose derivatives (sugar 1,5-dicarbonyls). Some reactions of the hexos-5-uloses were studied, and in some cases septanoside (seven-membered-ring saccharide) derivatives were isolated. Novel routes to D-xylo-hexos-5-ulose and D-lyxo-hexos-5-ulose
所描述的工作涉及从6-脱氧己基-5-烯吡喃糖苷中分离和表征环氧化物以及对其合成潜力的初步探索。延长的环氧化反应时间导致其原位水解,并得到新颖的受保护的D-己糖5糖衍生物(糖1,5-二羰基糖)。研究了己糖5 uloses的一些反应,并在某些情况下分离了七糖苷(七元环糖)衍生物。还描述了在肌醇和氮杂糖的合成和生物合成中作为中间体而感兴趣的D-木糖基己糖5-ulose和D-木糖基己糖5-ulose的新途径。通过NMR和X射线晶体学方法确定了环氧化物和新型5-己糖的结构。
