Apramycin is a structurally unique member of the 2-deoxystreptamine class of aminoglycoside antibiotics characterized by a monosubstituted 2-deoxystreptamine ring that carries an unusual bicyclic eight-carbon dialdose moiety. Because of its unusual s

The clinical aminoglycoside antibiotic gentamicin is a mixture of several difficult-to-separate major and minor components. The relative inaccessibility of the minor components in particular complicates efforts to separate antibacterial activity from

The synthesis of C-aryl/alkyl 2C-branched sugar-fused isochromans by using a carbohydrate-derived starting material is described. Our approach makes use of sequential Prins and Friedel–Crafts cyclizations in which a Perlin aldehyde derived homoally

We describe the preparation of methyl 5α-methyl-α- d -glucopyranoside and of 5α-fluoro-β- d -glucopyranose per acetate and the NMR-based conformational analysis of their side chains. Both the 5α-methyl and 5α-fluoro substituents increase the po

Differently substituted ascorbic-acid-derived allylic alcohols were used to study the Overman rearrangement under thermal and palladium-catalysed conditions. It was found that protection of the δ alcohol substituent as a a tert-butyldimethylsilyl et

We have developed a new catalyst system comprising AuCl3 and phenylacetylene that promotes the Ferrier rearrangement of glycals and 2-acetoxymethylglycals with different nucleophiles, and also the O-glycosylation of 1-O-acetyl sugars to obtain a vari

A few bicyclic hybrid sugar molecules comprising of oxa-aza, oxa-oxa, and oxa-carbasugar fused skeletons were designed and synthesized from C-2 acetoxyglucal involving Ferrier rearrangement, Grignard addition, and ring-closing metathesis as key steps
