Symmetrical and unsymmetrical archaeal tetraether glycolipid analogues have been prepared. The syntheses are based upon the elaboration of lipid cores from versatile chiral starting materials followed by simultaneous or sequential introduction of polar headgroups. Three pathways (A-C) were elaborated for the synthesis of stereochemically defined lipids 14-16 characterized by a straight bridging spacer
已经制备了对称和不对称的古细菌四醚糖脂类似物。合成是基于从多种手性起始原料精制脂质核心,然后同时或相继引入极性头基。阐述了合成立体化学定义的脂质14-16的三个途径(AC),这些脂质的特征是直连接间隔基和两个分别在sn-3和sn-2位置与甘油单元相连的二氢香茅烷基链。途径C似乎对于合成四醚9特别有利,该四醚9具有在嗜热嗜酸脂质中发现的环戊烷单元。通过二醇14-16与β-D-半乳糖呋喃糖基供体31的反应,以49-53%的产率生产了二糖基化脂质4-6。
