Herein we describe a simple and practical methodology for accessing both the α-anomers (d-mannose, N-acetyl-d-glucosamine, N-acetyl-d-galactosamine, d-lactose) and α- and β-anomers (d-glucose, d-galactose, l-fucose) of 2′-azidoethyl and azidotriethylene glycol glycosides using free sugars and Dowex 50 (resin) as an efficient catalyst. These azidoalkyl glycosides are increasingly useful synthetic intermediates for glycotechnology.
本文描述了一种简单实用的方法,能够获取2′-氮杂乙基和氮杂三乙烯二醇糖苷的α-异构体(d-甘露糖、N-乙酰-d-葡萄糖胺、N-乙酰-d-半乳糖胺、d-乳糖)以及α-和β-异构体(d-葡萄糖、d-半乳糖、l-岩藻糖),采用游离糖和Dowex 50(树脂)作为高效催化剂。这些氮杂烷基糖苷在糖科技中越来越成为有用的合成中间体。
