Unsaturated carbohydrates. Part XV. The synthesis of (3′-deoxyhex-2′-enopyranosyl)purine derivatives
Abstract
Fusion of 3-deoxyhex-2-enopyranosyl esters or the isomeric 2-hydroxyglycal esters with theophylline or 2,6-dichloropurine in the presence of an acidic catalyst affords (3′-deoxyhex-2′-enopyranosyl)purine nucleoside derivatives. Anomeric configurations can be assigned by n.m.r. methods.
