Article abstract of DOI:10.1055/s-1988-27787

By careful choice of the cyclization conditions (solvent, concentration of cesium hydroxide, high dilution) several strained heterocyclic metacyclophanes could be obtained in dramatically increased yields.The favorable effect of cesium hydroxide on the yield was proven.
