• Trapping the Oxyallyl Cation Intermediate Derived from the Nazarov Cyclization of Allenyl Vinyl Ketones with Nitrogen Heterocycles

  intermediate of the Lewis acid‐initiated Nazarov cyclization of an allenyl vinyl ketone (AVK) was trapped by pyrroles and indoles. The yields ranged from modest to high (up to 93%), and in both cases, only two of the three possible products were produced. Cyclopent‐2‐enones substituted at the 5‐position were predominantly produced, however with increasing alkyl substitution or placement of an electron‐withdrawing

  路易斯酸引发的烯丙基乙烯基酮（AVK）的Nazarov环化的阳离子中间体被吡咯和吲哚捕获。产量从中等到高（高达93％）不等，在两种情况下，只生产了三种可能产品中的两种。主要产生在5位取代的环戊2-烯酮，但是随着烷基取代的增加或氮上吸电子基团的放置，还可能形成替代的区域异构体。这项研究的结果表明，在电子上优选的位置是相对于氧烯丙基阳离子的氧的位置α，而对于更立体地阻碍反应的配偶体则优选环外位置。

  C–H bonds has become a dominant research theme in the past decade as an approach to efficient synthesis. However, the incorporation of carbon monoxide into such reactions to form valuable ketones has to date proved a challenge, despite its potential as a straightforward and green alternative to Friedel–Crafts reactions. Here we describe a new approach to palladium-catalysed C–H bond functionalization

  在过去的十年中，作为有效合成方法的一种金属催化方法的开发已成为一个主要的研究主题，以使C-H键惰性化。然而，迄今为止，将一氧化碳掺入此类反应以形成有价值的酮已证明是一项挑战，尽管它有潜力作为Friedel-Crafts反应的直接和绿色替代品。在这里，我们描述了一种新的钯催化的C–H键官能化方法，其中一氧化碳用于驱动高能亲电试剂的生成。这提供了一种方法，可以将金属催化的C-H官能化（稳定和可用的试剂）和亲电酰化（广泛的范围和选择性）的有用特征耦合在一起，并从芳基碘化物，CO和芳烃简单地合成酮。尤其，该反应以分子间方式进行，没有导向基团，并且钯催化剂的负载量非常低。机理研究表明，该反应通过强效的芳基三氟甲磺酸酯亲电子试剂的催化积累而进行。

  oxidative C-2 arylation followed by sulfonyl migration is described. The simple, easy access to the highly functionalized free-NH pyrroles secures opportunities for the preparation of compounds with promising biological activities in contemporary organic synthesis. The event of sulfonyl migration from pyrrole-N to C-3 is thermodynamically favored as revealed by density functional methods. The different plausible
