2-C-Methylene-N-glycosyl amides have been obtained from 2-(hydroxymethyl)glycals through a facile aza-Claisen rearrangement. This rearrangement has also been utilized in the synthesis of L-allo-deoxynojirimycin, a moderate inhibitor of human lysosomal α-mannosidase (IC50 = 64 μM), and two new C-5-(hydroxymethyl) analogues of L-altro-deoxynojirimycin and L-ido-deoxynojirimycin.(© Wiley-VCH Verlag GmbH
2-C-亚甲基-N-糖基酰胺已通过简单的氮杂-克莱森重排从 2-(羟甲基)糖基中获得。这种重排也被用于合成 L-allo-deoxynojirimycin,一种人溶酶体 α-甘露糖苷酶的中度抑制剂 (IC50 = 64 μM),以及 L-altro-deoxynojirimycin 的两种新的 C-5-(羟甲基)类似物和L-ido-脱氧野尻霉素。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
