  Metacyclophanes and related compounds. 22. Medium-sized cyclophanes. Preparation and valence tautomerism of 8,16-disubstituted [2.2]metacyclophane-1,9-dienes

  摘要：

  Introduction of functional groups other than hydrogen or alkyl groups into the internal positions of [2.2]metacyclophane-1,9-dienes was attempted. [2.2]Metacyclophane-1,9-dienes 6a-6g, bearing variously halogen, methoxy, and methyl substituents in the 8 and 16 positions, were prepared from the corresponding bis(halomethyl)benzenes 1 and bis(mercaptomethyl)benzenes 2 involving use of Wittig rearrangement of 2,11-dithia-[3.3]metacyclophanes followed by Hofmann elimination. Although 6a-6c, 6f, and 6g were isolated as thermally stable crystals, isolation of 6d failed since this compound was thermally labile and transformed spontaneously into 2,7-di-tert-butyl-1-chloropyrene (7). The photochemical and thermal valence tautomerizations of [2.2]metacyclophanes which were prepared in the present work are described. Attempts to convert 8,16-disubstituted [2.2]metacyclophane-1,9-dienes 6 to 4,5,9,10-tetrabromo-10b,10c-disubstituted 10b,10c-dihydropyrenes by treatment of these compounds with bromine in carbon tetrachloride failed but instead gave addition products 13 and transannular reaction products 14. The reaction pathways of the bromination are also discussed.

  Synthesis of Dibenzopyrenes and Pyrenes via Photolytic Sulfur Extrusion and Intramolecular Cross-Coupling Reactions of Dithia[3.3](1,3)naphthalenophanes and Dithia[3.3]metacyclophanes

  摘要：

  The syntheses of several substituted dithia[3.3]metacyclophanes and dithia[3.3](1,3)naphthalenophanes are reported and their photolyses in triethyl or trimethyl phosphite are described. Under these conditions, the corresponding tetrahydrodibenzopyrenes and tetrahydropyrenes are produced in a one-pot procedure when the precursor dithianaphthalenophanes and dithiacyclophanes possess at least one intraannular methoxyl group. A mechanism with supporting evidence is proposed to account for these results. Structural determinations of the four isomeric 11,22-dimethoxy-2,13-dithia[3.3](1,3)naphthalenophanes by NMR and X-ray single-crystal diffraction studies are also described. The syntheses of the novel anti-transoid- and anti-cisoid-[2.2](1,3)naphthalenophanes are also described.

  Homothiacalix[n]arenes have been largely underexposed compared with related (homo)heteracalixarenes, although their inherent structural features are particularly attractive for supramolecular host–guest chemistry. In this contribution, the synthetic macrocyclization protocols that afford homothiacalix[n]arenes have been reinvestigated and optimized, providing straightforward access to the parent h

  与相关的（同）杂acalixarenes相比，homothiacalix [ n ]芳烃在很大程度上暴露不足，尽管它们的固有结构特征对于超分子宿主-客体化学特别有吸引力。在此贡献中，对提供了高硫杂杯[ n ]芳烃的合成大环化方案进行了重新研究和优化，从而可以直接访问母体高硫杂杯[4]芳烃骨架。此外，还成功进行了内缘（双和四）酯官能化和二亚甲基桥氧化反应。溶液相（可变温度）NMR光谱研究和固态X射线结构提供了有关新型大环化合物构象特征的补充信息。
