Several Pd-catalyzed reactions were explored to further functionalize the bromo-substituted 4-amino-1,2,4,5-tetrahydro-2-benzazepin-3-one scaffold (Aba). We report in this paper suitable reaction conditions for Suzuki, Buchwald–Hartwig, and Heck reactions. The substitution pattern of the starting aminobenzazepinone turned out to be crucial for the success of these transition metal-catalyzed reactions
探索了几种钯催化的反应,以进一步官能化溴取代的4-氨基-1,2,4,5-四氢-2-苯并ze庚因-3-酮骨架(Aba)。我们在本文中报告了Suzuki,Buchwald–Hartwig和Heck反应的合适反应条件。事实证明,起始氨基苯并ze庚酮的取代方式对于这些过渡金属催化的反应的成功至关重要,这通常需要对标准文献程序进行修改。Pd催化的方法提供了对Aba支架的新型取代模式的访问。
