Abstract

The S-isomers of four racemic sec-alcohols, which possess a chiral centre at the α-position to the hydroxy group, were oxidized to the corresponding ketones whereas the R-isomers remained unreacted on a TEMPO-modified graphite felt electrode in the presence of (-)-sparteine, where the enantiopurity of the remaining R-isomers was >99% and the current efficiency for the produced ketones was >90%.
