  Palladium-Catalyzed Direct Arylation of Polysubstituted Benzofurans

  摘要：

  An efficient access to 2-substituted 3-arylbenzofurans through a palladium-catalyzed C3 direct arylation of 2-substituted benzofurans with aryl bromides is described. The scope and limitation of this reaction was studied. The method tolerates a variety of functional groups on the aryl halide and has been successfully extended to polysubstituted benzofurans to obtain the corresponding 3-arylbenzofurans with good to excellent yields.

  通过在Arynes上级联环化法合成2-芳基苯并呋喃

  摘要：

  通过级联[2 + 2]，然后在芳烃上进行[4 + 1]环化，已经开发出了2-芳酰基苯并呋喃的高效合成途径。通过将瞬时的芳烃插入N，N-二甲基甲酰胺中，然后用硫内鎓盐捕集，通过形成邻醌甲基化物来进行整体转化。而且，该转变具有高官能团耐受性的广泛的基板范围。该新反应已成功用于有效的CYP19芳香酶抑制剂的合成和对生物活性复合物雌酮的后期功能化。

  日期：——

  strategy for the direct synthesis of 2-aroyl benzofurans from aryne precursors has been developed. This reaction proceeds via C–O and C–C bond cleavage as well as C–O and C–C bond formation in a single reaction vessel. The methodology provides good yields of 2-aroyl benzofurans and tolerates a variety of functional groups. The synthesized 2-aroyl benzofurans were further benzoylated at 3-positions and

  The highly efficient and expedient route for the syntheses of 2-aroyl benzofurans has been developed via the cascade [2+2] followed by a [4+1] annulation on arynes. The overall transformation proceeded through the formation of ortho-quinone methide by the insertion of transient aryne into N,N-dimethylformamide and subsequent trapping with sulfur ylide. Moreover, this transformation has a broad range
