Abstract

Abstract: Starting from tetraacetylribofuranose 1 and 2, 6-dichloropurine 2, in the presence of p-toluenesulfonic acid (p-TsOH), 2′, 3′, 5′-tri-O-acetyl-2, 6-dichloropurine nucleoside 3 has been synthesized in microwave oven for the first time. On comparing (→ Comparing) with the conventional methods, this method has advantages such as shorter reaction time (4.5 min), better yield (83.5%), simple (→ simpler) workup and environmental acceptability.
