摘要

The three pardcyclophanes (I) with the 3-and 4-, 4-and 5-, and 5-and 5-membered methylene bridges have been prepared. These syntheses further illustrate the generality of the method involving hydrogenation of the benzene rings prior to an acyloin ring closure followed by dehydrogenation at a later stage. The stereochemistry of the fully hydrogenated pardcyclophanes is discussed.
