Orthocyclophanes. 2. Starands, a New Family of Macrocycles of Spirobicyclic Polyketals with a 2n-Crown-n Moiety

Synthesis and functionalization of higher members of the n>orthocyclophanes, or n>OCPs, have been investigated.Oxidation of the benzylic methylenes in n>OCPs gave the polyoxo derivatives.Exhaustive oxidation of all methylenes in even-numbered n>OCPs gave rearranged isomers of the cyclopolyketal structure instead of the corresponding polyoxo derivatives.We propose the class name "starands" for this new family of crown compounds for their star-shaped crown ether structure.Detailed synthesis and characterization of two starands are described.

Organic Reactions Catalyzed by Solid Superacids. 9. Friedel-Crafts Cyclobenzylation of Benzene with Bis-(hydroxymethyl)diarylalkanes Catalyzed by a Perfluorinated Sulfonic Acid Resin (Nafion-H)

Cyclobenzylation of benzene using bis(hydroxymethyl)diarylmethanes (6) and bis(hydroxymethyl)diarylaethanes (14) in the presence of solid perfluorinated sulfonic acid resin, Nafion-H, as a catalyst results in novel bridged aromatic compounds, 10,15-dihydro-5H-tribenzocyclononenes (15) and metacyclophanes (17), respectively.The reactions were clean, and water that was formed as a by-product did not deactivate the catalyst.It was also found that cyclobenzylation products, methacyclophanes were not formed via the isomerization of the corresponding orthomethacyclophane (19) under the reaction conditions used.The posible mechanism of the reaction is also discussed.
