    Heterocyclic derivatives of sugars: an NMR study of the formation of 1-glycosyl-3,5-dimethyl-1 H-pyrazoles from hydrazones
    摘要:
    Hydrazones were prepared by treatment of monosaccharides and disaccharides with hydrazine hydrate and converted in high yield to mixtures of 1-glycosyl-3,5-dimethyl-1 H-pyrazoles by reaction with pentan-2,4-dione (acetylacetone). The isomeric products were separated by HPLC and characterized by NMR spectroscopy. This represents a new approach to the introduction of a heteroaromatic label into sugars under nonacidic and nonreducing conditions, and it is a process likely to be especially useful for glycan hydrazones obtained from glycoproteins by hydrazinolysis or beta elimination in the presence of hydrazine.

    acid 2. Cyclocondensation of 2 with hydrazine hydrate, phenyl hydrazine, semicarbazide and thiosemicarbazide gave the pyridazinone derivatives 3a-d. Reaction of 3a with POCl(3) for 30 min gave the chloropyridazine derivative 4a, which was used to prepare the corresponding carbohydrate hydrazone derivatives 5a-d.

    Abstract New 3-( d - galacto -pentitol-1-yl)pyrazole derivatives have been obtained by the reaction of d -galactose hydrazones and nitroalkenes. Cyclodehydration of the 1-methyl-3-( d - galacto -pentitol-1-yl)pyrazoles in trifluoroacetic acid at room temperature afforded good yields of 3-(α- d -lyxofuranosyl)-1-methyl derivatives. A β anomer was obtained only for the 5-( p -tolyl) derivative.

  • Sequential removal of monosaccharides from the reducing end of oligosaccharides. I. A reaction between hydrazine and sugars having a glycosidic substituent on a carbon atom adjacent to the carbonyl group
    作者:Brad Bendiak、Mary Ellen Salyan、Mario Pantoja
    DOI:10.1016/s0040-4039(00)75790-x
    日期:1994.1
    Hydrazine reacts smoothly with sugars having a glycosidic substituent when the glycosyl moiety is located on a carbon atom adjacent to an aldehyde or keto group, resulting in cleavage of the glycosidic linkage. In excess hydrazine, the released glycoside forms a hydrazone from which the reducing sugar may be recovered in high yields.

    formed in various proportions from d -glucose, d -mannose, l -arabinose, and d -xylose by the action of refluxing hydrazine. Sequential hydrazinolysis, catalytic hydrogenation, and chromatography afford a route to 1,2-dideoxyalditols. For example, 1,2-dideoxy- l -erythro-pentitol is formed from l -arabinose in 42% yield, and d -xylose is a source of 1,2-dideoxy- d -threo-pentitol (50%). Under the conditions
    摘要在回流肼的作用下,由d-葡萄糖,d-甘露糖,l-阿拉伯糖和d-木糖以各种比例形成1,2-二脱氧醛糖醇,相应的1-烯烃和1-脱氧醛糖醇。顺序肼解,催化氢化和色谱法提供了通往1,2-二脱氧醛糖醇的途径。例如,由1-阿拉伯糖以42%的收率形成1,2-二脱氧-1-戊-戊醇,而d-木糖是1,2-二脱氧-d-苏-戊醇的来源(50%)。在蒙特勒(Montreuil)用于糖蛋白和糖肽肼解的条件下(无空气下在100°C的无水肼放置30小时),没有形成1,2-二脱氧醛糖醇。降解不完全,存在一些醛糖。在Kochetkov的肼解条件下(用硫酸肼在105°下放置10 h),
