Methylhydrazine-induced α-hydroxylation of β-dicarbonylcompounds was achieved using O2 as the oxygen source. This reaction provides an efficient approach to enantioenriched ɑ-hydroxy β-dicarbonylcompounds, which are valuable substances and widely used in the chemical and pharmaceutical industry. A wide variety of β-keto esters could undergo this oxidation to give the corresponding products in excellent
