A multicomponent reaction of indane-1,3-dione, an aldehyde and an amine-containing aromatic compound leading to the formation of indenopyridine-based heterocyclic medicinal scaffolds has been investigated. It was found that the yields significantly improve when oxygen gas is bubbled through the reaction mixture, facilitating the oxidation of the intermediate dihydropyridine-containing compounds to their aromatic counterparts. Investigation of the reaction scope revealed that formaldehyde, as well as various aliphatic, aromatic and heteroaromatic aldehydes, works well as the aldehyde component. In addition, substituted anilines and diverse aminoheterocycles can be utilized in this process as the amine-containing component. Preliminary biological evaluation of the synthesized library identified a pyrimidine-based polycycle, which rivals the anticancer drug etoposide in its toxicity and apoptosis inducing properties toward a human T-cell leukemia cell line.
研究人员对茚-1,3-二酮、一种醛和一种含胺芳香化合物的多组分反应进行了研究,该反应可生成以茚并吡啶为基础的杂环药物支架。研究发现,如果在反应混合物中通入氧气,可促进中间的含二氢吡啶化合物氧化成芳香族对应化合物,从而显著提高产量。对反应范围的研究表明,甲醛以及各种脂肪族、芳香族和杂芳香族醛类都能很好地用作醛组分。此外,取代的苯胺和各种氨基杂环也可作为含胺组分用于该过程。通过对合成的化合物库进行初步生物评估,发现了一种嘧啶基多环化合物,它对人类 T 细胞白血病细胞系的毒性和诱导细胞凋亡的特性可与抗癌药物依托泊苷相媲美。
