the construction of the medicinally important 3-substituted-3-hydroxyoxindole and its 3-spirocyclic derivatives with readily available aniline derivatives as starting materials. This highly atom- and step-economical one-pot protocol was carried out under metal-free base- mediated conditions through a novel oxidative annulation strategy with oxygen as the oxidant. The key intermediates were isolated
