Supramolecular methods for controlling intermolecular [2+2] photocycloaddition reactions of unsaturated compounds in solutions

This review deals with the methods of supramolecular chemistry used for controlling the efficiency and stereoselectivity of intermolecular [2+2] photocycloaddition of olefins and other unsaturated compounds in homogeneous solutions. The best-studied methods are self-assembly through cation–macrocycle interactions, complexation with molecular templates through hydrogen bonding, and confinement of the reactants in supramolecular containers. The possibilities of using anionic templates and combined supramolecular approaches are discussed.
