  钯催化苯并呋喃-2-基甲基乙酸酯与亲核试剂的 Tsuji-Trost 型反应。

  摘要：

  研究了钯催化的苯并呋喃-2-基甲基乙酸酯与 N、S、O 和 C 软亲核试剂的类苄基亲核取代反应。反应的成功很大程度上取决于催化体系的选择：对于氮基亲核试剂，反应与 Pd2(dba)3/dppf 反应良好，而对于硫、氧和碳亲核试剂 [Pd(η3-C3H5)Cl] 2/XPhos 效率更高。区域化学结果表明，亲核取代仅发生在 η3-(苯并呋喃基)甲基配合物的苄位上。高至优异的产率和实验程序的简单性使该方案成为制备 2-取代苯并[b]呋喃的通用合成工具。

  A microwave-enhanced, solventless Mannich condensation of terminal alkynes and secondary amines with para-formaidehyde on cuprous iodide doped alumina has been developed. beta-Aminoalkynes are generated in good yields. The reaction can be extended to include a cyclization, which affords 2-substituted benzo[b]furans. The chemoselectivity of the reaction indicates that terminal alkynes are much more reactive than enolizable ketones under the reaction conditions. (c) 2005 Elsevier Ltd. All rights reserved.

  palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd2(dba)3/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(η3-C3H5)Cl]2/XPhos is more efficient
