  In this paper we report an efficient pot-economic methodology for the synthesis of ortho-olefinated biaryls. This has been achieved through an atom-economic threefold cross-coupling of triarylbismuth reagents with 2-halobenzaldehydes followed by pot-economic in situ Wittig olefination. The overall process is a pot-economic straightforward synthesis of ortho-olefinated biaryls from 2-halobenzaldehydes, triarylbismuth reagents and phosphonium salts. This pot-economic approach was applied to the formal synthesis of medicinally important Eupomatilone-6.

  An inter- followed by an intramolecular double Heck reaction of bridged o,o′-dibromobiaryls with ethyl acrylate is described. The nature of the bridging atom/group determined the outcome of the reaction. This double Heck reaction strategy afforded a safe and convenient synthesis of 9-(ethoxycarbonylmethylene)-9H-xanthene and a novel route to 9 and/or 10-substituted anthracene derivatives.

  在过去的几十年中，在C H活化和烯化反应中，邻位导向基团的快速增长。在本文中，我们以各种邻位取代基团的方式解决了这些烯化产物的光诱导的E  →  Z异构化。最初，我们发现邻苯并恶唑基芳基丙烯酸酯在365 nm直接辐射下有效地进行了E  →  Z异构化（产率高达88％）。此外，在C H活化和烯化反应中对其他5个导向基团进行研究发现，乙酰氨基基团也可以是增强E  →  Z的良好邻位取代基团。异构化。对照实验表明，取代位置对于光诱导的异构化或[2 + 2]环加成至关重要。最后，普遍有趣的荧光猝灭/变化现象总是伴随着异构化。X射线单晶法揭示了异构化过程对丙烯酸芳基酯片段进行了显着的共轭变形，我们认为这种变化可能有助于荧光和吸收剂的减少。
• Synthetic Applications of <i>o-</i> and <i>p</i>-Halobenzyl Sulfones as Zwitterionic Synthons:  Preparation of <i>O</i><i>rtho-</i>Substituted Cinnamates and Biarylacetic Acids

  日期：2002.7.1

  The synthetic applications of o-halobenzyl and p-halobenzyl sulfones as precursors of 1,3- and 1,5-zwitterionic synthons, respectively, are described. Their alpha-sulfonyl carbanions, generated by means of the phosphazene base P-2-Et or BuLi or K2CO3 under PTC conditions, reacted with different electrophiles such as alkyl halides, aldehydes, and electrophilic olefins. Palladium-catalyzed cross-coupling processes such as Heck, Suzuki, and Sonogashira reactions can be efficiently performed at the halogen atom. These two sequential functionalization processes are applied to the synthesis of ortho-substituted cinnamates and pharmaceuticals belonging to the family of p-biarylacetic acids such as 4-biphenylacetic acid, namoxyrate, xenyhexenic acid, and bipherylpropionic acid.
