An unusual multiple isocyanide insertion reaction with methyleneindolinone using indium(III) chloride as the catalyst has been disclosed. This strategy allows for the rapid construction of structurally complex spirooxindole in an efficient manner. The present protocol features mild conditions, atom economy, and broad substrate scope.
