  摘要：

  2-Formyl-3-iodo-1 -tosylpyrrole 2 has been prepared in four steps from cinnamaldehyde. It was coupled with a wide variety of arylboronic acids to give the corresponding biaryl compounds in high yields. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.

  Suzuki cross-coupling reactions of 3-pyrroleboronic acid derivatives with haloaromatics and the reverse process i.e., the coupling of 3-iodo(bromo)pyrroles with arylboronic acids have been investigated as a potential key step in the synthesis of (–)-rhazinilam and analogues. It was found that 3-iodo-2-formyl-1-tosylpyrroles efficiently coupled with a variety of arylboronic acids in the presence of PdCl₂(dppf) as catalyst. This catalytic system is compatible with a broad spectrum of arylboronic acids — electron-rich, electron-poor, hindered, heterocyclic — which easily coupled with the pyrrole substrate.Key words: 2-substituted-3-arylpyrroles, biaryls, coupling reactions, arylboronic acids, palladium coupling, catalysis.

  铜促进3-吡咯硼酸衍生物与卤代芳香烃的Suzuki交叉偶联反应，以及反向过程即3-碘(溴)吡咯烷与芳基硼酸的偶联反应已被研究作为合成(–)-拉洁嗪和类似物的潜在关键步骤。发现3-碘-2-甲酰基-1-对甲苯磺酰基吡咯烷在PdCl₂(dppf)催化剂存在下有效地与各种芳基硼酸偶联。该催化系统与广泛的芳基硼酸兼容，包括富电子、贫电子、障碍、杂环化合物，这些都可以轻松地与吡咯底物偶联。关键词：2-取代-3-芳基吡咯、联苯、偶联反应、芳基硼酸、钯偶联、催化。
