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

the extremely complex pathogenesis. Accumulating evidence indicates there is a close relationshipbetween several enzymes and Alzheimer's disease. Various substituted 3-arylcoumarin derivatives were synthesised, and their in vitro activity, including cholinesterase inhibitory activity, monoamineoxidaseinhibitory activity, and antioxidant activity were investigated. Most of the compounds exhibited

Abstract A variety of substituted 3-arylcoumarin derivatives were synthesised through microwave radiation heating. The method has characteristics of environmental friendliness, economy, simple separation, and purification process, less by-products and high reaction yield. Those 3-arylcoumarin derivatives were screened for antioxidant, α-glucosidase inhibitory and advanced glycation end-products (AGEs)
An improved chemical reaction protocol with short time and easy work-up was described here for 2-phenylbenzofuran derivatives. The final purified products, 2-phenylbenzofuran derivatives 5a—g and the intermediate diols 4a—g, were evaluated for their estrogen receptor (ER) binding affinity and selective activity in vitro. Among these fourteen tested compounds, 4g and 5g showed higher binding affinity on ER subtypes, ERα and ERβ. Compound 4g exhibited preferable ERα binding, while 5g was more estrogen selective for ERβ. The molecular docking was also performed to explore the detailed interactive interface between ER and the compounds.
