title: Disiloxane-protected 2-deoxyribonolactone as an efficient precursor to 1,2-dideoxy-1-beta-aryl-D-ribofuranoses.
abstract: [formula: see text] Aryl C-nucleosides are analogues of natural nucleosides where the bases have been replaced with aromatic moieties. Work herein describes the highly stereoselective syntheses of non-hydrogen-bonding carbocyclic derivatives using a disiloxane-protected 2-deoxy-D-ribono-1,4-lactone as a stable and readily accessible starting material. Unlike the bis(TBDMS)-protected congener, this compound enables the use of sterically congested ortho-substituted aryllithium reagents in the initial addition reaction.
