A concise synthetic route is described for the synthesis of gabosine A and N. The key step uses a zinc-mediated tandem reaction where methyl 5-deoxy-5-iodo-2,3-O-isopropylidene-β-D-ribofuranoside is fragmented to give an unsaturated aldehyde which i

The synthesis of branched and conformationally restricted analogs of the anticancer nucleosides 3′-C-ethynyluridine (EUrd) and 3′-C-ethynylcytidine (ECyd) is presented. Molecular modeling and 1H NMR coupling constant analysis revealed that the fu

[reaction: see text] A new synthesis of (+)-cyclophellitol, a potent beta-glucosidase inhibitor, has been completed in nine steps from D-xylose. The key transformations involve a zinc-mediated fragmentation of benzyl-protected methyl 5-deoxy-5-iodo-x

Three protected 3'-C-branched LNA-type phosphoramidite building blocks 17, 27, and 38, containing furanose rings locked in an N-type conformation, were synthesized from a known 3-C-allyl allofuranose derivative using strategies relying on the introdu
