  Pd-Catalyzed C–H Carbonylation of (Hetero)arenes with Formates and Intramolecular Dehydrogenative Coupling: A Shortcut to Indolo[3,2-c]coumarins

  摘要：

  An efficient protocol for the synthesis of (hetero)aryl carboxylic esters has been achieved by Pd-catalyzed CH carbonylation of (hetero)arenes with aryl formates. A relatively wide range of functional groups can be tolerated in this transformation, and the corresponding esters are obtained in good yields. On this basis, an intramolecular oxidative CH/CH coupling has been developed to prepare indolo[3,2-c]coumarins.

  A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields

  已开发出用于合成 indole-3-carboxylates 的可见光诱导的吲哚与酚的羰基化反应。该反应通过自由基羰基化过程进行，其中使用元素 I 2作为有效的光敏引发剂，从而避免使用过渡金属催化剂。以中等至良好的产率制备了一系列不同的芳基吲哚-3-羧酸酯。几种含酚天然产物和药物的后期功能化进一步突出了该方法的广泛适用性。

  Pd-catalysed decarboxylative Suzuki reactions and orthogonal Cu-based O-arylation reactions of aromatic carboxylic acids are reported. The new reactions may provide alternative routes for the synthesis of some biaryls and aromatic carboxylic esters.

  钯催化的脱羧Suzuki反应和芳香族羧酸的正交Cu基O-芳基化反应已有报道。新的反应可能为某些联芳基和芳族羧酸酯的合成提供替代途径。
