Upon electrolysis, the initial suspension of 1 turned homogeneous over 24 h. TLC analysis showed an incomplete but clean conversion, and NMR analysis revealed 80% conversion to 3-keto product 1a. In particular, the apparent full selectivity for the C3-position and the clean conversion to the keto-sugar demonstrated the potential of this method. The use of graphite electrodes, being inexpensive, pleasingly led to full oxidation of 1 within the same reaction time (Scheme 2).
