  Syntheses of Syn and Anti Doublebent [5]Phenylene

  摘要：

  [GRAPHICS]The parent and dipropyl-substituted anti (1a,b) and syn doublebent (2a,b) [5]phenylenes have been assembled by CpCo-catalyzed double cyclization of regiospecifically constructed appropriate hexaynes. H-1 NMR, NICS, and an X-ray structural analysis of is reflect the aromatizing effect of double angular fusion on the central ring of the linear [3]phenylene substructure.

  The latter then rapidly loses carbon monoxide to produce the ultimate acetylenic product. Despite their high photoreactivity, cyclopropenones were found to be thermally stable compounds with the exception of hydroxy- and methoxy-substituted cyclopropenones. The latter undergo rapid solvolysis in hydroxylic solvents even at room temperature. The application of this reaction to the in situ generation

  烷基，芳基和杂原子取代的环丙烯酮的UV照射导致一氧化碳损失并形成相应炔烃的定量收率。光化学脱羰反应的量子产率从烷基取代的环丙烯酮的20％到30％到二苯基和二萘基环戊烯酮的70％以上。通过使用激光闪光光解法观察到该反应中中间体迅速形成（<5 ns），然后稍微慢一些（约40 ns）衰变。DFT计算使我们能够将这种中间体鉴定为由环丙烯酮环的碳-碳键之一裂解形成的两性离子物质。后者然后迅速损失一氧化碳以产生最终的炔属产物。尽管它们的光反应性很高，除羟基和甲氧基取代的环丙烯酮外，发现环丙烯酮是热稳定的化合物。后者甚至在室温下也能在羟基溶剂中进行快速溶剂分解。该反应对苯二炔结构原位生成的应用通过苯并二烯化的苯二炔12的光化学制备进行了说明。
• Synthesis and Unusual Reactivity of <i>N</i>-Tosyl-4,5-benzoazacyclodeca-2,6-diyne, Yneamino-Containing Enediyne

  Substitution of the propargylic carbon for nitrogen in cyclic 10-membered ring enediynes results in at least 2 orders of magnitude enhancement of reactivity. The mechanism of cycloaromatization of aza-enediynes, however, switches from radical (Bergman) to polar, which proceeds by initial protonation of a reactive yneamine moiety. Ketenimmonium cation produced on this step undergoes intramolecular nucleophilic cyclization. Reaction is strongly catalyzed by acids and exhibits substantial kinetic isotope effect.

  A hydroamination-double hydroarylation cascade using aniline derivatives bearing a trienyne moiety as the substrate was efficiently promoted by a gold(I) catalyst to produce benzo[a]naphtho [2,1-c]carbazole derivatives in good yields. This reaction is applicable to various substituted trienyne-type anilines, including 2,3-diethynylthiophene derivatives. The reaction of anilines bearing a tetraenyne and pentaenyne moiety allows direct construction of highly fused carbazoles by tetra- and pentacyclization, respectively, through hydroamination and consecutive hydroarylation without producing any theoretical waste products from the substrates.
