[reaction: see text] A novel total synthesis of 3',5'-C-branched uridine azido acid has been accomplished using stereoselective aldehyde alkynylation, Ireland-Claisen rearrangement, and iodolactonization as the key reactions. Compared to traditional routes that start from carbohydrates, the present methodology is more efficient, flexible for future optimization, and provides access to both enantiomers
[反应:见正文]使用立体选择性醛烷基炔化,爱尔兰-克莱森重排和碘内酯化为关键反应,完成了3',5'-C-支链尿苷叠氮酸的新型全合成。与从碳水化合物开始的传统路线相比,本方法更有效,更灵活,可用于将来的优化,并提供了产品的两种对映异构体的途径。因为关键化学反应不涉及3'-和5'-C取代基,所以我们的方法是3',5'-C烷基核苷类似物的通用方法。
