Abstract
: Organocatalyst 1,4-diazabicyclo [2.2.2]octane (DABCO) has proven to be an efficient and environmentally friendly catalyst in the multicomponent reaction involving aldehydes, ethylenediamine, and thioglycolic acid under microwave conditions. DABCO stands out among other organic catalysts due to its costeffectiveness, non-toxic nature, and environmentally conscious profile. The method employed in this study exhibited exceptional attributes, such as high yields, swift reaction times, atom economy, catalyst reusability, and minimal catalyst loading. Additionally, there were excellent yields of products (90-94%). The melting points, UV-Vis, IR, 1HNMR, 13CNMR, were used to analyze the produced compounds. The in-vitro antibacterial activity of the synthesized compounds was investigated against pathogenic strains E. coli and Bacillus supstalis, and the results obtained were further explained with the help of DFT and molecular orbital calculations. Moreover, the compound 4b was found to be the most potent antibacterial agent amongst all tested compounds. result: Bis-thiazolidinones derivatives have been synthesized in excellent yields (90–94%) by mixing of aldehydes (2 mmol), ethylenediamine (1 mmol), thioglycolic acid (2 mmol), using DABCO (0.5 mmol), in 8 to 10 minutes under microwave irradiation.
期刊介绍:
Current Organic Chemistry aims to provide in-depth/mini reviews on the current progress in various fields related to organic chemistry including bioorganic chemistry, organo-metallic chemistry, asymmetric synthesis, heterocyclic chemistry, natural product chemistry, catalytic and green chemistry, suitable aspects of medicinal chemistry and polymer chemistry, as well as analytical methods in organic chemistry. The frontier reviews provide the current state of knowledge in these fields and are written by chosen experts who are internationally known for their eminent research contributions. The Journal also accepts high quality research papers focusing on hot topics, highlights and letters besides thematic issues in these fields. Current Organic Chemistry should prove to be of great interest to organic chemists in academia and industry, who wish to keep abreast with recent developments in key fields of organic chemistry.
