Ph3P/I2–Et3N-mediated one-pot two-step esterification–cyclization toward 3-aryl coumarins and 3-aryl-4-methylcoumarins is reported. The reaction of a variety of aryl acetic acids containing steric or reactive group with 2-hydroxybenzaldehydes or 2′-hydroxyacetophenone proceeded smoothly at room temperature to afford the corresponding products in good to excellent yields using inexpensive and readily
An ultrasound-assisted one-pot acylation/cyclization reaction between N-acylbenzotriazoles and 2-hydroxybenzaldehydes has been developed for the synthesis of substituted 3-arylcoumarins. Using ultrasound not only allows rapid and clean conversion but also simplifies experimental setup and parallel workup leading to rapid generation of 3-arylcoumarin libraries under mild, solvent-free, and chromatography-free

In pursuit of more effective cancer treatments, researchers embarked on a study to enhance the coumarin derivative’s therapeutic potential. These compounds, known for their anticancer properties, have faced challenges such as increased toxicity and drug resistance. The research aimed to design, synthesize and assess new 3-phenyl coumarin derivatives specifically for breast and lung cancer treatment. Utilizing 3-oxoacyl-reductase (1T8I), a series of compounds were synthesized from aromatic aldehydes and phenylacetic acid. Among the synthesized 11 compounds that were examined, compounds C01, C04, C05 and C08 had significant cytotoxic effects on both MCF-7 and MRC-5 cell lines. Particularly, compound C08, featuring ethoxy and nitrate substitution, exhibited remarkable potential against both cancer cell lines, emphasizing its promise for further exploration in cancer therapy.
