Sequential addition of up to six components under well-defined conditions results in the formation of novel structures with amino acid, peptide, and heterocyclic components. This process forms up to eight new bonds under very mild conditions and tolerates a broad spectrum of functional groups.

在明确定义的条件下连续添加多达六种成分会导致形成具有氨基酸、肽和杂环成分的新结构。这个过程在非常温和的条件下形成多达八个新键,并且可以容忍广泛的官能团。采用 Groebke-Blackburn 三组分反应与 Ugi 四组分或 Passerini 三组分反应的正交联合来合成多官能化杂环。在面向多样性的合成方面,基本多环结构上的10个位置可以变化。直接批量拆分为制备结构复杂的类似物提供了一种简单有效的方法。
