  摘要：

  The palladium-catalyzed addition of aryl- and alkenylboronic acids to 4-hydroxy-2-alkynecarboxylates and in situ lactonization would constitute a novel methodology for the synthesis of various butenolides with an excellent stereoselectivity and a high control of regioselectivity.

  The reaction of aryl iodides with alkyl 4-hydroxy-2-alkynoates in the presence of formic acid, tri-n-butylamine and a palladium(II) catalyst provides a convenient route to functionalized substituted butenolides through a one pot hydroarylation/cyclization reaction. In the presence of formic acid, tri-n-butylamine and a palladium(II) catalyst, alkyl 4-hydroxy-2-alkynoates undergo a one pot hydrogenation/cyclization

  在甲酸，三正丁胺和钯（II）催化剂的存在下，芳基碘化物与4-羟基-2-链烷酸烷基酯的反应提供了通过一锅加氢芳基化/环化反应制备官能化取代丁烯化物的便捷途径。在甲酸，三正丁胺和钯（II）催化剂的存在下，烷基4-羟基-2-链烷酸酯经过一锅加氢/环化反应生成丁烯内酯环。通过增加过量的甲酸，可以观察到饱和γ-内酯的直接形成。以高的立体选择性进行反应，并且在加氢芳基化的情况下，具有良好的区域选择性。
