摘要

摘要：在加热条件下，通过 D-核糖对甲苯磺酸盐、苯胺和环烯酮的单锅立体选择性三组分反应合成了一系列半饱和融合多环亚氨基糖。由亚胺离子衍生的 N-芳基烯胺是反应的关键中间体。通过这种方法，在 80 °C 下通过正常的 Diels-Alder 机理获得了各种新型复合融合亚氨基糖。这种策略将有助于制备具有结构多样性的生物活性亚氨基糖类似物。

One-Pot Synthesis of Semisaturated Fused Polycyclic Iminosugars by a Diels-Alder Reaction

Abstract: A series of semi-saturated fused polycyclic iminosugars were synthesized by one-pot stereoselective three-component reactions of D-ribose tosylate, aniline and cycloenones under heating conditions. The N-aryl enamine derived from an iminium ion is the key intermediate for the reaction. In this way, various novel complex fused iminosugars were obtained through a normal Diels-Alder mechanism at 80 °C. This strategy will enable the preparation of bioactive iminosugar analogues with structural diversity.
