Electrocatalyric Oxidation on an (S)-Enantioselective Chiral Tempo-Modified Electrode
(6S, 7R, 10R)-1-aza-4-amino-2, 2, 7-trimethyl-10-isopropylspiro[5.5]undecane-1-yloxyl (Chiral TEMPO)-modified electrode was prepared by attaching this mediator chemically to the carboxyl groups of thin poly(acrylic acid) (PAA) layer coated on graphite felt (GF). Preparative electrolysis of racemic sec-alcohols and diols on Chiral TEMPO-modified GF electrode proceeded electrocatalytically in the presence of achiral base such as 2,6-lutidine, and yielded the corresponding products with high current efficiency and (S)-enantioselectivity.
