With these first results in hand, we investigated the substrate scope of the oxidation reaction, employing graphite electrodes. In order to facilitate solubility and chromatographic purification, partly protected glycosides were used, leading to the corresponding products in moderate to good yields (Table ). Reaction conditions: glycoside (0.32 mmol, 1 eq), quinuclidine (0.3 eq), Me4NBF4 (1 eq), HFIP (10 eq), 5 mL ACN, graphite electrodes, 5 mA (constant current, 2.00 mA/cm 2 ), 16 h, yields after column chromatography. a Reaction on 0.56 mmol scale. b Reaction on 0.16 mmol scale for 24 h. c NMR yield using 1,4-difluorobenzene as internal standard.
