The de novo synthesis of racemic 1â²,4â²-dimethyluridine was accomplished in 12 steps starting from 2,5-dimethylfuran and vinylene carbonate. Key steps of the sequence include the stereoconvergent preparation of a meso diacid, and a stereoselective glycosylation without neighboring group participation. Such 1â²,4â²-disubstituted ribonucleoside analogues are undisclosed compounds, which may present interesting biological activities.
从 2,5-二甲基呋喃和碳酸乙烯酯开始,经过 12 个步骤完成了外消旋 1,4,4,2-二甲基尿苷的从头合成。这一系列的关键步骤包括立体转换制备中位二元酸,以及无邻近基团参与的立体选择性糖基化。这种 1â²,4â²-二取代的核糖核苷类似物是未公开的化合物,可能具有有趣的生物活性。
