Oxidation of primary and secondary alcohols, using catalytic amounts of TEMPO and tetra-n-butylammonium bromide in combination with periodic acid and wet alumina in dichloromethane is compatible with a broad range of functional groups and acid-sensitive protecting groups. The system also enables a chemoselective oxidation of secondary alcohols in the presence of primary alcohols.
