title: Synthesis of the C1-phosphonate analog of UDP-GlcNAc.
abstract: We describe the first synthesis of the C1-phosphonate analog of UDP-GlcNAc, based on a new preparation of the corresponding glycosyl phosphonate. This C-glycosyl analog is shown to be a very weak inhibitor (Ki>10 mM) of fungal chitin synthase, indicating that at least in this case the replacement of the anomeric oxygen with a methylene group is not an innocent substitution.
