UDP-sugar analogs are useful for the study of glycosyltransferases and the production of unnatural glycans. The preparation of five UDP-GlcNAc derivatives is reported with 6-deoxy, 6-azido, 6-amino, 6-mercapto, or 6-fluoro substitutions. A concise chemoenzymatic synthesis was developed using the kinase NahK (B. longum JCM1217) and the uridyl transferase GlmU (E. coli K12).
