Description

technical field

[0001] The invention relates to the field of synthesis and application of important intermediates of carbohydrate compounds with biological activity. Background technique

[0002] Natural oligosaccharides or sugar conjugates have good biological activities in terms of physiology and pharmacology (Schmidt, R.R.; Kinzy, W. Adv. Carbohydr. Chem. Biochem. 1994, 50, 21-23), and the more attention they receive getting closer. So far, there have been a lot of literature reports on the synthesis of carbohydrate compounds. In these synthetic strategies, a very important step is the regioselective removal of anomeric carbon-oxygen-acyl groups, and then converting the obtained anomeric carbon-hydroxyl compounds into active reaction donors for the synthesis of oligosaccharides. For this reason, there are many method reports that can realize this purpose, for example, ammonia (Mikano, M.Carbohydr.Res.1989,191,150-153), benzylamine (Conchie, J.; Levvy, G.A.Methods Carboh...
