Abstract
Indirect electrocatalytic selective oxidation of the secondary hydroxy group in 3,24-dihydroxy-5β-cholane was performed using atmospheric oxygen in the presence of copper(I) complex with a polymeric 2,2′-biquinoline-containing ligand as catalyst. The reaction was characterized by a high yield (85%), 100% selectivity, and mild conditions, the CuII/CuI redox potential being −0.55 V relative to Ag/AgCl/KCl.
