Abstract

A graphite felt electrode modified with (6S, 7R, 10R)-4-amino-2, 2, 7-trimethyl-10-isopropyl-1- azaspiro [5.5] undecane N-oxyl was prepared for electrocatalytic oxidation of diols; electrolysis of diols on the modified electrode yielded optically active lactones (92.0–96.4%), with an enantiopurity of 82–99% ee.
