We present a convenient synthesis of novel heterocyclic structures containing pyrrolo[1,2-a][1,4]diazepine fragment 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.
我们提出了使用四组分Ugi缩合的新型修饰方便合成包含吡咯并[1,2- a ] [1,4]二氮杂卓片段的新型杂环结构。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。
