摘要:
For a long time, the Suzuki-Miyaura cross-coupling reaction could not be used for the synthesis of 2,2'-bipyridines due to the lack of sufficiently stable 2-pyridylboron compounds. Stabilized 2-pyridylboronic acid esters recently developed by Hodgson, however, were found to be ideally suited for this purpose. Two general protocols could be developed and demonstrated to be valuable alternatives, which can be used very efficiently for the synthesis of functionalized 2,2'-bipyridines.
