超越自然界所能产生的分子多样性的扩展是化学科学的基本目标。尽管含硼杂环的化学性质很丰富,但以六元B 3 NO 2核为特征的1,3-二氧杂-5-氮杂-2,4,6-三硼烷(DATB)环系统仍然难以捉摸。在这里,我们报告m的合成-三联苯基为模板的DATB衍生物,由于三个适当排列的硼原子而显示出高稳定性和奇特的Lewis酸度。我们确定了羧酸和胺的脱水酰胺化中DATB的特殊用途,该反应具有很高的学术和工业重要性。与先前报道的催化剂和酰胺偶联剂的作用机理相反,提出了三个硼位参与底物组装,降低了过渡态的熵成本。由DATB核心决定的独特的机理途径不仅会促进这种酰胺化反应,还会促进由多位点激活引起的其他反应。
