摘要
An unusual aromatization to perbenzylated 3,5-dihydroxy-6-(hydroxymethyl)-2-pyridone was demonstrated utilizing sugar lactam, under strong basic conditions, derived from D-Galactose. 2-Pyridone was efficiently converted into a pharmaceutically relevant structure 3,5-dihydroxy pyridine salt to demonstrate its synthetic utility. This result is the first report for 2-pyridone synthesis from a carbohydrate, and also first of its kind for a novel 3,5-dihydroxypyridine. (C) 2013 Elsevier Ltd. All rights reserved.
