Sažetak
Coumarins are a class of compounds widely distributed in plant kingdom, but lots of synthetic work has been done on them in the last few decades as well. Most synthetic routes utilize various toxic solvents and catalysts, leaving a significant environmental impact and tendency today is to reduce such negative impact whenever possible. For such purpose, deep eutectic solvents are often used. Deep eutectic are often used as green media for many synthetic routes and are often characterized as environmentally friendly [1-3]. Their application in organic synthesis and extraction, as well as an extensive analysis of their properties were described in some recent reviews [1-6]. The aim of our work was to synthesize a novel coumarinyl Schiff bases utilizing choline chloride/malonic acid based deep eutectic solvent as reaction media. Previously, a series of Schiff bases was synthesized [7] in our laboratory conventionally, but we have noticed their formation when deep eutectic solvents are applied. No need for specific catalyst, like acetic acid which is often used in these kinds of reactions, was noticed, since this eutectic solvent acted as a catalyst as well. Not only did we get a novel compounds, we applied an environmentally friendly approach, utilizing a solvent made of biodegradable components, with low toxicity and vapor pressure which can be easily recycled and reused.
