摘要

The direct oxidation of UDP-alpha-D-glucose and UDP-N-acetyl-alpha-D-glucosamine to the corresponding uronic acids was explored using either TEMPO or platinum-catalysed oxidation with molecular oxygen. Whilst TEMPO-based procedures gave rise to substantial over-oxidation and/or degradation of UDP-glucose, oxidation of UDP-N-acetyl-glucosamine to UDP-N-acetyl-glucosaminuronic acid was achieved with > 90% conversion and ca. 65% isolated yield using a platinum-catalysed procedure.
