Synthesis of a β-Ketophosphonate Bioisostere of UDP-N-acetylglucosamine

Authors


Abstract

A concise route to a new β-ketophosphonate analog of glycosyl nucleotides is described. Such a diphosphate bioisostere is a stable mimic of enzyme substrates involved in peptidoglycan biosynthesis and will be the starting point for the development of new potential antibiotics. The synthesis is carried out by condensing a lithiomethylenephosphonate derivative on a methyl N-acetylglucosaminylacetate followed by esterification with a uridine derivative.
