  Site-selective Suzuki–Miyaura reactions of 2,3,5-tribromo-N-methylpyrrole

  摘要：

  The first Suzuki-Miyaura reactions of 2,3,5-tribromo-N-methylpyrrole are reported. These reactions proceed with very good site-selectivity in favour of position 5 which is more reactive than position 2, due to steric reasons. The second attack occurs at position 2 which is more electron deficient than position 3. (C) 2011 Elsevier Ltd. All rights reserved.
