摘要

本研究报道了亚氨基糖 DAB 的合成以及 1-脱氢丹诺尻霉素（DMJ）和相应哌啶醇酸的歧化合成。关键步骤包括肼基羧酸苄酯和烯丙基胺分别对 D-木糖二呋喃酸酯和 D-葡萄糖二呋喃酸酯的双亲核置换。然后对生成的双环苷进行水解、氧化或还原。

Stable Ditriflates of D-Glucose in the Synthesis of Iminosugars and Polyhydroxylated Pipecolic Acids

A synthesis of the iminosugar DAB and a divergent synthesis of 1-dehydromannojirimycin (DMJ) and the corresponding pipecolic acid are reported. The key step consists of double nucleophilic displacements of a D-xylose ditriflate by benzyl carbazate and a D-glucose ditriflate by allyl amine, respectively. This is followed by hydrolysis and oxidation or reduction of the resulting bicyclic glycosides.
