Reactions of various heterocycles 1–6 with N-bromosuccinimide in the presence or absence of water have been studied for side chain versus ring bromination to afford some new and important heterocyclic synthons. Interestingly, the N-bromosuccinimide reaction in the presence of perchloric acid, a new condition, affords exclusively the new dibromo aminopicoline 1f, which is not obtained by other presently
对于侧链与环溴化反应,研究了各种杂环1-6与N-溴琥珀酰亚胺在有水或无水条件下的反应,以提供一些新的重要的杂环合成子。有趣的是,在高氯酸存在下的N-溴琥珀酰亚胺反应(一种新条件)仅提供了新的二溴氨基吡啶1f,这是目前其他研究方法无法获得的。
