标题:Enzymatic method for synthesis of carbohydrates
发明人：NILSSON KURT
摘要:A synthetic method in which is included at least one process, which is characterized by that a glycosidase (EC 3.2) is used to catalyse a reaction between a partially protected galactose derivative, or a partially protected glucose derivative, and a glycosyl doner, which is an oligosaccharide or a monosaccharide glycoside, is described. The process is suitable for synthesis of carbohydrate derivatives or for synthesis of partially protected carbohydrate intermediates which are suitable for further synthesis e.g. of blood group determinants A and B, or other carbohydrates.

标 题 :Solvent-free synthesis of ethereally substituted blocked monosaccharides and the selective hydrolysis thereof
发明人：ARORA SUDERSHAN K
权利人:GREENWICH PHARMA
摘要:A solvent-free method for synthesizing an ethereally-substituted, blocked monosaccharide comprising the steps of: n 1) mixing, in the absence of solvent, a partially blocked monosaccharide unblocked at one position, an alkyl halide or a substituted alkyl halide, and an anhydrous alkali base; n 2) heating the mixture to a temperature sufficient to allow the mixture to react; n 3) maintaining the mixture at a suitable temperature for a time sufficient to form an ethereally-substituted blocked monosaccharide and drive off any water produced; n 4) removing any unreacted alkyl halide or substituted alkyl halide from the mixture; n 5) recovering the ethereally-substituted blocked monosaccharide product from the mixture; and, optionally, n 6) selectively hydrolyzing the ethereally-substituted blocked monosaccharide product to remove one or more of the acetal blocking groups.
