Sugar enolones: synthesis, reactions of preparative interest, and γ-pyrone formation

Abstract

An account on pyranoid sugar enolones is given with respect to their preparation, their use as educts for the synthesis of a variety of 2-deoxy and 4-deoxy sugars functionalised via the enol or carbonyl function, and their conversion into y-pyrones, allowing an evaluation of the biosynthetic pathways for kojic acid and maltol from carbohydrate precursors.
