A de novo asymmetric synthesis of α-ido-pyranosides, as well as several deoxy and amino variants, has been achieved. The procedure involves a palladium(0)-catalyzed glycosylation in combination with a Wharton rearrangement/epoxide-opening reaction sequence to access sugars with ido, manno, and colito stereochemistry as well as several azido analogues.
已经实现了 α-ido-吡喃糖苷以及几种脱氧和氨基变体的从头不对称合成。该程序涉及钯 (0) 催化的糖基化与沃顿重排/环氧化物开环反应序列相结合,以获取具有 ido、甘露糖和大肠立体化学以及几种叠氮基类似物的糖。
