The first total syntheses of the antineoplastic glycoside (+)-phyllanthoside (1) and the parent disaccharide (-)-phyllanthose (5) have been achieved. Stereoselective Koenigs-Knorr coupling of two 6-deoxyglucose derivatives, bromide 54 and alcohol 55, generated the uncommon 1? ? 2beta glycosidic linkage of (-)-phyllanthose. A stereochemically convergent Mitsunobu reaction of protected disaccharide 87 with aglycon carboxylic acid 80, prepared via asymmetric synthesis, then led to 1 of high enantiomeric purity. The Mitsunobu procedure comprises an efficient general method for stereospecific assembly of beta-glycosyl esters.

In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10.

Benzyl, benzoyl, and acetyl protected 1-OH and 1-SH glycoses in the glucose, glucosamine, galactose, mannose, and lactose series react with nitrobenzenes activated by one or two electron withdrawing substituents like nitro and cyano to afford the corresponding aryl glycosides in 50-100% yield. The SNAr displacement of nitrite by 1-OH glycoses is reversible and gives predominantly the alpha-glycosides, whereas 1-SH glycoses do not anomerize and afford the beta-glycosides. Thus, the prepared dicyanophenyl gycosides are useful building blocks for the preparation of phthalocyanine-glycoconjugates via template synthesis.

Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.10343-06-3, C14H20O10. A document type is Article, introducing its new discovery., Formula: C14H20O10

Model O-glycosylation reactions at either rim of calix[4]arenes are described with the aim of providing access to a new family of carbohydrate-containing calixarene derivatives named calixsugars. One or two sugar moieties (D-mannofuranose and D-glucopyranose) were introduced at the lower rim of the parent calix[4]arene by glycosylation of the phenolic hydroxyl groups by means of a Mitsunobu reaction. Tetrapropoxy calix[4]-arenes bearing two or four hydroxy-methyl groups at the upper rim were coupled with perbenzoylated thioethyl D-galactoside and D-lactoside in the presence of the thiophilic promoter copper(II) triflate. In this way beta-linked bis and tetrakis-O-galactosyl calix[4]arenes were obtained in good yield, the latter showing some solubility in water. For the O-lactosyl derivatives only the bis-substituted compound could be obtained because of the competing formation of an intramolecular ether linkage between 1,3-hydroxymethyl groups. Preliminary binding studies showed some affinity of the galactose-containing calixsugars toward charged carbohydrates and dihydrogen phosphate anion.

(Chemical Equation Presented) To achieve site specific delivery of nitric oxide (NO), a new class of glycosidase activated NO donors has been developed. Glucose, galactose, and N-acetylneuraminic acid were covalently coupled to 3-morphorlinosydnonimine (SIN-1), a mesoionic heterocyclic NO donor, via a carbamate linkage at the anomeric position. The beta-glycosides were successfully prepared for these conjugates, while the alpha-glycosidic compounds were very unstable. The new stable sugar-NO conjugates could release NO in the presence of glycosidases. Such NO prodrugs may be used as enzyme activated NO donors in biomedical research.
