Deoxygenation/dimerization of sugar derivatives with BF3· Et2O-Et3SiH: Synthesis of a β-isonucleoside

Lewis acid-Et3SiH induced deoxygenation of anomeric carbon of sugars generates tetrahydrofuran derivatives, accompanied by hitherto unknown dimeric products. If the reagent addition steps are reversed, tetrahydrofuran derivatives are obtained a

Simple entry into isonucleosides: Synthesis of 6-amino-9-[(3S,4S,5R)-4- hydroxy-5-(hydroxymethyl)tetrahydrofuran-3-yl]purine

A simple and efficient method for the preparation of isonucleoside 7 is described. The preparation of 1,4-anhydroxylitol 4, a key intermediate, is described by intramolecular cyclization of (2S,3R,4R)-3,5-dibenzyloxypentan-1,2, 4-triol 3 using diethyl car
