Graphical Abstract
Cavity control: A highly selective 1,4-addition reaction of a toluene derivative to o-quinones proceeds efficiently within a self-assembled coordination cage (see scheme). The cage accelerates the formation of the 1,4-adduct but suppresses all other reaction pathways that are normally favorable in the absence of the cage.
