A diversity-oriented approach comprising a Ugi four-component reaction and gold(I)-catalyzedhydroarylationunder very mild reaction conditions has been elaborated. This gives direct access to the synthesis of biologically important heterocycles such as pyrrolopyridines, pyridoindoles, and azepinoindoles in very good yields. The influence of the nucleophilicity of the heterocycle and the mode of ring
已经详细阐述了一种面向多样性的方法,包括在非常温和的反应条件下的 Ugi 四组分反应和金 (I) 催化的加氢芳基化。这提供了直接合成生物学上重要的杂环,如吡咯并吡啶、吡啶并吲哚和氮杂吲哚的方法,产率非常好。讨论了杂环亲核性和闭环方式的影响。
