The generation of a small and representative library of 3,5,8-trisubstituted coumarins (21 compounds, 7 families, 3 groups) is described. The library was built from the corresponding propargyl vinyl ethers and three different 1,3-dicarbonyl derivatives using a one-pot coupled domino strategy. These coumarins constitute a novel chemotype defined by the presence of a chemical handle in the pyranone ring
描述了一个3,5,8-三取代香豆素(21个化合物,7个家族,3个组)的小型且有代表性的文库的生成。使用一锅耦合多米诺策略,由相应的炔丙基乙烯基醚和三种不同的1,3-二羰基衍生物构建该文库。这些香豆素构成了新颖的化学型,其定义为吡喃酮环中存在化学手感以及修饰芳环的变化取代模式,该芳族环包括含氟或含氧的官能团。
