  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.

  日期：1999.10

  The Suzuki-Miyaura palladium-catalyzed coupling reaction was extended to achieve mixed cross-coupling between substituted aryl and naphthyl mono- and bisbromomethanes with phenylboronic acid, 1-methoxy-2-naphthyl-, 3-methoxy-2-naphthyl-, or 4-methoxy-1-naphthylboronic acid to form the corresponding disubstituted methanes.

  扩展了Suzuki-Miyaura钯催化的偶联反应，以实现取代的芳基和萘基单和双溴甲烷与苯基硼酸，1-甲氧基-2-萘基，3-甲氧基-2-萘基或4的混合交叉偶联。 -甲氧基-1-萘基硼酸形成相应的二取代甲烷。
