In vitro antifungal activity of polyfunctionalized 2-(hetero)arylquinolines prepared through imino Diels–Alder reactions
摘要:
Diverse polyfunctionalized quinolines, easily prepared using Lewis acid-catalyzed imino Diels-Alder reactions between corresponding aldimines, were tested for antifungal properties against standardized as well as clinical isolates of clinically important fungi. Among them, 4-pyridyl derivatives displayed the best activities mainly against dermatophytes. The activity appears not to be related neither to the lipophilicity nor to the basicity of compounds.

A study on interaction between N-(4-pyridinyliden)anilines 1-4 and 2,2-dimethoxypropane under Kametani reaction conditions was realized. According to the GC-MS analysis of crude reaction, besides the needed 4-methyl-2-(4-pyridinyl)quinolines 5-8, three collateral products: secondary amines 9-12, 4-(2-methylprop-1-enyl)quinolines 13-16 and 4-(2-methoxy-2-methylpropyl)quinolines 17-20 were formed.
