synthetic approach to skeletally diverse alkaloid-like compounds, involving two consecutive three-component reactions, was developed. First, reaction between a range of secondary amines, carbonyl compounds and triazines yielded cyclic imines. Crucially, the identity of the substituents in the amine and carbonyl compound components determined ― through a "folding" pathway - the alkaloid-like scaffold that was
开发了一种合成方法来合成骨架多样的类生物碱化合物,涉及两个连续的三组分反应。首先,一系列仲胺、羰基化合物和三嗪之间的反应产生环状亚胺。至关重要的是,胺和羰基化合物组分中取代基的身份确定 - 通过“折叠”途径 - 制备的生物碱样支架。环状亚胺产物是第二个反应的底物,最常见的是与异氰化物和羧酸的 Joullie-Ugi 反应。因此,最终产品通常最终来自五个单独的组件,并且每个支架的替代品的广泛和独立变化是可能的。这 43 个产品基于 28 个不同的图节点级框架。
