  Cross-coupling study of iodo/chloropyridines and 2-chloroquinoline with atom-economic triarylbismuth reagents under Pd-catalysis

  摘要：

  This study describes the palladium-catalyzed couplings of iodopyridines, chloropyridines, and chloroquinoline with atom-economic BiAr3 reagents in sub-stoichiometric loadings. Mono-arylations of iodo and chloropyridines produced arylpyridines in high yields. The couplings addressed with dihalopyridines have afforded chemo- and regio-selective coupling products. Arylations of 2-chloroquinoline with different triarylbismuth reagents demonstrated fruitful coupling reactivity under the established conditions. This sumptuous study demonstrates the remarkable cross-coupling reactivity of iodo/chloropyridines and chloroquinoline with triarylbismuth reagents. (C) 2014 Elsevier Ltd. All rights reserved.

  of isoflavone via cross-coupling reaction of 3-trifloxychromone and triarylbismuth as a threefold arylating reagent. These isoflavones were further converted into 3,4-diarylpyrazole and 4,5-diarylpyrimidine using hydrazine hydrate and guanidinium chloride in the successive step in the same pot. Interestingly the formation of 3,4-diarylpyrazole was achieved in the shortest reaction time i.e., 30 min

  摘要本研究揭示了从3-trifloxychromone和triarylbismuth开始的一锅操作中3,4-二芳基吡唑和4,5-二芳基嘧啶的形成。一站式操作中，整个过程包括两个步骤。第一步通过作为三重芳基化试剂的3-三氟甲氧基色酮和三芳基铋的交叉偶联反应导致异黄酮的形成。在同一罐中的后续步骤中，使用水合肼和氯化胍将这些异黄酮进一步转化为3,4-二芳基吡唑和4,5-二芳基嘧啶。有趣的是，在最短的反应时间即在室温下也达到了30分钟，就形成了3,4-二芳基吡唑。 图形概要 提要此处介绍的工作描述了一种新的方法，该方法可通过一锅操作从3-三氟甲氧色酮和三芳基铋开始形成具有医学重要性的杂环3,4-二芳基吡唑和4,5-二芳基嘧啶。

  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.
