Benzene‑1,3,5‑tricarboxylic acid‑functionalized Cherry gum as a novel and recoverable nanocatalyst for efficient synthesis of 1,4-polyhydroquinoline derivatives

In this study, Benzene-1,3,5-tricarboxylic acid (BTA)-functionalized gum (Cherry gum) (gum-Pr-BTA), as a novel nanocatalyst was prepared. This novel nanocatalyst was used for the expeditious and efficient synthesis of 1,4-polyhydroquinoline derivatives, as an important pharmaceutical scaffold, in ethanol reflux conditions. This method has several advantages such as high yields, low catalyst loading, short reaction times, and simple workup and could be used up to five reaction cycles without a noticeable decrease in catalytic activity.
