We present a convenient synthesis of novel pyrrole- and indole-fused 1-oxo-1,2,3,4-tetrahydropyrazine heterocyclic structures using a novel modification of four-component Ugi condensation. We demonstrate the usefulness and versatility of the developed approach for the synthesis of variously substituted compounds, and discuss the scope and limitations of the chemistry involved.
我们提出了一种方便的合成新型吡咯和吲哚稠合的1-氧代-1,2,3,4-四氢吡嗪杂环结构,采用四组分Ugi缩合的新型修饰方法。我们证明了开发的方法用于合成各种取代的化合物的实用性和多功能性,并讨论了所涉及化学的范围和局限性。
