A highly efficient protocol for acid-mediated peri-annulation of perimidines with pyrimidines was developed. Pyrimidines, used as surrogates for 1,3-dicarbonyl compounds allow for furnishing benzo[gh]perimidines, including hardly available analogs, non-substituted, or mono-substituted at C-6, C-8. Limitations of reactions employing 5-bromopyrimidines are investigated.
开发了一种用于酸介导的嘧啶环化环化的高效方案。用作 1,3-二羰基化合物替代物的嘧啶允许提供苯并[gh] 嘧啶,包括几乎无法获得的类似物、未取代的或在 C-6、C-8 处单取代的类似物。研究了使用 5-溴嘧啶的反应的局限性。
