A novel methodology for asymmetric synthesis of 2-amino-2-deoxy sugars is developed, starting from readily available chiral building block 1 and 2,3-O-isopropylideneglyceraldehyde 2, via Julia olefination and subsequent dihydroxylation as key steps. The versatility of this approach is exemplified by the preparation of L-glucosamine, L-mannosamine and L-talosamine derivatives in highly diastereometrically
对于2-氨基-2-脱氧糖不对称合成一种新颖的方法进行显影,从容易获得的手性结构单元开始1和2,3- Ò -isopropylideneglyceraldehyde 2,经由 朱莉娅烯化以及随后的二羟基化是关键步骤。这种方法的多功能性可以通过以下方法得到证明:L-氨基葡萄糖, L-甘露糖胺和非对映体纯形式的L -talosamine衍生物。
