文摘

Formation of Ba2+ templated “sandwich” dimers of crown-derivatized styrylheterocycles was studied. Supramolecular dimerization provides preorganization for regio- and stereoselective [2+2] photocycloaddition. The [2+2] photocycloaddition yields only one cyclobutane isomer out of eleven possible.
