novel features of a Groebke-Blackburn-Bienaymé cyclocondensation are established and discussed. The heterocycles obtained were evaluated for their antibacterial activity and several of them demonstrated a weak antimicrobial effect, but for most of the compounds a 30-50% increase in biomass of Gram-positive strains (mainly B. subtilis) compared to control was observed.
在 Ugi 和 Groebke-Blackburn-Bienaymé 多组分反应中,对著名的
氨基唑、
3-氨基-5-甲基异恶唑和 5-
氨基-N-芳基-1H-
吡唑-4-甲酰胺作为胺组分进行了研究。发现了
氨基唑在 Ugi 四组分反应中应用的第一个例子,并建立并讨论了 Groebke-Blackburn-Bienaymé 环缩合的新特征。对获得的
杂环化合物的抗菌活性进行了评估,其中一些化合物显示出较弱的抗菌作用,但对于大多数化合物而言,观察到与对照相比,革兰氏阳性菌株(主要是
枯草芽孢杆菌)的
生物量增加了 30-50%。
