A RhIII‐catalyzed tandem CH activation and CN bond formation reaction between oximes and diazo compounds for the synthesis of heterocycle‐fused pyridine N‐oxides has been developed. The reaction exhibits good functional group tolerance and regioselectivity. After simple transformation, the 1‐substituted, 1,3‐disubstituted, 1,4‐disubstituted and 1,3,4‐trisubstituted heterocycle‐fused pyridines were
已经开发了一种Rh III催化的肟和重氮化合物之间的串联CH活化和C bondN键形成反应,用于合成杂环稠合的吡啶N-氧化物。该反应表现出良好的官能团耐受性和区域选择性。经过简单的转化,就可以高效获得1-取代的,1,3-二取代的,1,4-二取代的和1,3,4-三取代的杂环吡啶。此外,该策略也已扩展到合成关键中间体,以构建一种潜在的抗HIV药物。
