New Three- and Sixfold Bridged Phenylogous Cyclophanes

The syntheses of the threefold bridged cyclophanes 4, 5, of the sixfold bridged cyclophane 6, and of the triple-layered cyclophanes 7, 8 are reported.The yields have been optimized by variation of the reaction conditions and by use of the cesium effect.The enantiomer resolution of 7 and the X-ray structural analysis of 4 are discussed.

Chemistry of Heterocyclic Compounds. 55. Synthesis and Conformational Studies of Substituted 1,2-Diaryl- and Heteroarylbenzenes. Synthesis of Benzopyridinocyclophanes

The syntheses of 1,2-bis(3-methylphenyl)-, 1-(6-methyl-2-pyridyl)-2-(3-methylphenyl)-, and 1,2-bis(6-methyl-2-pyridyl)benzenes are described.The aryl and heteroaryl olefins were brominated and didehydrobrominated to give the corresponding acetylenes, whic
