Synthesis of the mannopeptimycin disaccharide and its conjugation with 4-alkylidene-β-lactams

The disaccharide moiety of the antibiotic mannopeptimycin has been synthesized as a (N-phenyl)trifluoroacetimidate donor, the reactivity of which was tested in conjugation with a 4-alkylidene-β-lactam acceptor. Key steps of the synthesis were Bi(OTf)

Synthesis of 1-deoxyhept-2-ulosyl-glycono-1,5-lactone utilizing α-selective O-glycosidation of 2,6-anhydro-1-deoxy-d-hept-1-enitols

A series of 1-deoxy-heptulo-2-pyranosyl-glycono-1,5-lactones were synthesized utilizing completely α-selective O-glycosidation of heptenitols. Anomeric configuration of the products was confirmed by 3JC,H coupling measurement and X-ray crystal structural analysis. The benzyl-protected ketosyl saccharides were partly unstable, and glycosidic linkage was prone to cleave under the usual debenzylation conditions. To prevent this, we surveyed various additives for the Pd-catalyzed hydrogenation reaction and found that basic alumina was the most effective.

Efficient installation of β-mannosides using a dehydrative coupling strategy

(Chemical Equation Presented) A new coupling procedure for the construction of the challenging β-mannosidic bond is described. Dehydrative mannosylation using 4,6-O-benzylidene mannopyranoses allows for the formation of β-mannosides in excellent yield. Th

Synthesis of a novel dioxan sialic acid analog

A preparative scale synthesis of a dioxan sialic acid analog was achieved from D-mannose. The conformation and the acidic character of this dioxan derivative, closely related to sialic acid, provides a scaffold for drug design.

Stereochemical Control in Hex-5-enyl Radical Cyclizations: From Carbohydrates to Carbocycles. 3

The hex-5-enyl radical cyclization reaction was applied to prepare highly oxygenated cyclopentanoids from aldopyranose sugars.The Wittig reaction of the sugars readily provides hex-5-en-1-ols which were converted to hex-5-enyl radicals via one of the vari
