previous methods. This synthetic approach, exemplified with 24 amidines and requiring only a single purification, highlights a multicomponent Ugi–Mumm rearrangement to afford highly diversified quinazolinones which undergo regiospecificrearrangement to afford new amidines. The method extensively broadens the structural scope of this new class of trisubstituted amidines and demonstrates the tolerance
开发了一种有效的四步六转化方案,以提供具有生物活性的N-烷基-或N-芳基酰胺( E )-芳基酰胺,其具有战略性的脒 C3 修饰,这是以前的方法无法获得或产量低的。这种合成方法以 24 种脒为例,只需要一次纯化,突出了多组分 Ugi-Mumm 重排以提供高度多样化的喹唑啉酮,这些喹唑啉酮经过区域特异性重排以提供新的脒。该方法广泛拓宽了这种新型三取代脒的结构范围,并证明了区域 C3 脒空间体积的耐受性,通过 X 射线晶体学分析可视化。
