combination of the recently developed multicomponent construction of highly substituted 3,4-dihydropyridones with subsequent allylation and intramolecular Heck-type cyclization allows the straightforward construction of benzo[a]quinolizines, a class of polycyclic compounds that – despite their interesting pharmacological and photochemical properties – have little precedent in the literature. After optimization
最近开发的高度取代的 3,4-二氢吡啶酮的多组分结构与随后的烯丙基化和分子内 Heck 型环化相结合,可以直接构建苯并 [a] 喹啉,这是一类多环化合物,尽管它们具有有趣的药理和光化学特性– 在文献中鲜有先例。在优化各个步骤后,我们使用这个可靠的三步序列来生成一个小库,其中包含多种取代的苯并 [a] 喹嗪和各种杂环类似物。
