Abstract
The S-isomers of four racemic sec-alcohols, which possess a chiral cen tre at the alpha-position to the hydroxy group, were oxidized to the c orresponding ketones whereas the R-isomers remained unreacted on a TEM PO-modified graphite-felt electrode in the presence of (-)-sparteine, where the enantiopurity of the remaining R-isomers was >99% and the cu rrent efficiency for the produced ketones was >90%.
