-glycopyranosides. Nitroxide spin-labeled α- d -glycopyranosides, as well as a β-maltoside, were synthesized by standard methods. The synthesis is also described of 2-amino-2-deoxy- d -glucose and - d -galactose derivatives having a spin label at C-2, and of the spin-labeled compound 1-[4-(β- d -galactopyranosyloxy)phenyl]-3-(2,2,6,6-tetramethylpiperidin-1-oxyl-4-yl)-2-thiourea.
摘要通过使过邻苄基-α-d-甘露糖基溴化物与2,2,6,6-四甲基-4-哌啶子醇反应,以高收率和高度立体选择性的方式合成了一氧化氮自旋标记的α-d-吡喃葡萄糖苷在Lemieux等人设计的溴离子催化条件下。氢解后,解封的中间体被氧化,得到所需的自旋标记的α-d-糖吡喃糖苷。用标准方法合成了一氧化氮自旋标记的α-d-糖吡喃糖苷以及β-麦芽糖苷。还描述了在C-2处具有自旋标记的2-氨基-2-脱氧-d-葡萄糖和-d-半乳糖衍生物以及自旋标记的化合物1- [4-(β-d-吡喃半乳糖基氧基)的合成。 )苯基] -3-(2,2,6,6-四甲基哌啶-1-氧基-1-基)-2-硫脲。
