Sol-gel entrapped TEMPO for the selective oxidation of methyl alpha-D-glucopyranoside

The sol-gel entrapment of TEMPO within a silica matrix yields an efficient and recyclable catalytic system for the selective oxidation of methyl ?-D-glucopyranoside (MGP) in water with NaOCl as primary oxidant, thus opening the way to the heterogeneous catalysis of the conversion of sugars into valuable uronates.
