This process involved the reaction of N-unprotected 5-bromoisatin-3-oximes and aryl-boronic acid derivatives under mild reactive conditions. Remarkably, the reaction exhibited tolerance towards several aryl-boronic acids containing diverse functional sensitivity subgroups (73% to 97% yields and 2 to 6 h). Extensive research has demonstrated that the (C=O) group present in 5-bromoisatin-3-oximes can serve as an inhibitory molecule or ligand, playing a crucial role in the generation of (E) oxindole nitrones.}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, year={2024}, month={Mar.}, keywords={Catalyst, Synthesis, Isatin, Copper acetate, Nitrones, Cascade reaction} }
