Racemic 1',4'-dimethyladenosine was prepared according to a stereoselective sequence from 2,5-dimethyl furan and vinylene carbonate. This sequence is short and efficient (nine steps) and relies on the desymmetrization of a meso diol, followed by the glycosylation of the anomeric position. The latter reaction was thoroughly studied, as it is the key step of the sequence, and very particular reactivity
根据立体选择性序列从 2,5-二甲基呋喃和碳酸亚乙烯酯制备外消旋 1',4'-二甲基腺苷。该序列短而有效(九个步骤)并且依赖于内消旋二醇的去对称化,然后是异头位置的糖基化。后一个反应被彻底研究,因为它是序列的关键步骤,并且观察到 1',4'-二甲基化糖的非常特殊的反应性。二次反应按照原始机制发生并产生原始副产物。
