A Cu-catalyzed tandem oxidation-intramolecular Cannizzaro reaction that converts α-hydroxyketones into valuable α-hydroxyesters under mild conditions is reported. The substrate scope encompasses biorenewable synthons and complex structures, such as steroids. We provided mechanistic insights using isotope labeling and rationalization by computational means.
