strategies. Demonstrated here is the reaction of TAms with sugar‐derived tetrahydrofuran (THF) aldehydes, obtained from the regioselective dehydration of biomass‐derived sugars, to provide access to cyclic aminodiols in high yields. In a preliminary study we have also established the direct transamination of sugars to give acyclic aminopolyols. Notably, the reaction of the ketose d‐fructose proceeds with
碳水化合物是生物质的主要组成部分,由于其成本低、易于获得和立体化学多样性,作为化学品、材料和生物燃料的可持续来源具有独特的潜力。为了升级碳水化合物以获得有价值的含氮糖类化合物(例如氨基多元醇),使用转氨酶(TAms)的生物催化胺化已被研究作为传统合成策略的可持续替代方案。这里展示了 TAms 与糖衍生的四氢呋喃 (THF) 醛的反应,该醛是通过生物质衍生的糖的区域选择性脱水获得的,从而以高产率获得环状氨基二醇。在一项初步研究中,我们还建立了糖的直接转氨基作用以产生无环氨基多元醇。值得注意的是,酮糖d-果糖的反应以完全立体选择性进行,产生高纯度的有价值的氨基糖。
