Dicarbonyl sugars are convenient substrates for the stereoselective synthesis of hydroxylated piperidines and pyrrolidines, via a double reductive amination reaction (NaCNBH3, MeOH). Using this strategy, 2,5-anhydro-imino-D-glucitol (1) and 1-deoxynojirimycin (3) were prepared from 5-keto-D-fructose (2, commercially available) and 5-keto-D-glucose (4), respectively.
二羰基糖是通过双重还原胺化反应(NaCNBH 3,MeOH)进行立体选择性合成羟基化哌啶和吡咯烷的便利底物。使用这种策略,由5-酮-D-果糖(2,可商购)和5-酮-D-葡萄糖(2,5-脱水亚氨基-D-葡萄糖醇(1)和1-脱氧野rim霉素(3))制备。4)。
