Microwave Assisted Highly Efficient Synthesis of Rhodanine and -2, 4-Thiazolidinedione Derivatives Under Solvent Free Conditions
Background: In the present study, we performed according to green chemistry’s standards, an easy and very efficient one-pot synthesis of2-thioxo-1,3-thiazolidin-4-one(rhodanine) and thiazolidine-2,4-dione (TZD) derivatives yin.Knoevenagel condensation of various aldehydes with rhodanine/ thiazolidine-2,4-dione in the presence of only 15 mole% of deep eutectic solvents (DESs) -choline chloride/urea- propionate and microwave radiation under solvent-free conditions Method: Twenty compounds were synthesized under thermal and microwave conditions and the yields of synthesized compounds were 77-9007O and 81-950, respectively. The IR spectra were obtained on a PerkineElmer FT-IR spectrophotometer using K.Br disks.itt NMR. and 13C NMR. of products were registered Bruker 500 spectrometer and chemical shifts are expressed as d (ppm) with tetramethylsilane (TMS) as an internal standard in.DNISO-d, as a solvent The purity of synthesized compounds was checked by chromatography and UV light (254 ran) was used for visualization. Result: A range of rhodanine and-2, 4-thiazolidinedione derivatives were synthesized using ChCll urea catalyst under solvent-free conditions at 80 C. Then, the sample derivatives were synthesized under optimum conditions Conclusion: The mild reaction conditions, good to excellent yields, easy workup, without the involxement of any harmful solvents/chemicals and easily available substrates, they all facilitated in the preparation of all synthesized compounds.
