Antioxidant and antitumor activities of 4-arylcoumarins and 4-aryl-3,4-dihydrocoumarins

Five 4-arylcoumarins (1c-g) and twelve 3,4-dihydro-4-arylcoumarins (2a-l) were synthesized and tested for antioxidant activity, antitumor activity, toxicity and structure-activity relationships analysis. 4-Arylcoumarins and 3,4-dihydro-4-arylcoumarins tha

Synthesis and NMR of 4-Aryl-3,4-dihydrocoumarins and 4-arylcoumarins

This paper described the synthesis and 1H and 13C NMR chemical shifts of a series of 4-aryl-3,4-dihydrocoumarin and 4-arylcoumarin derivatives based on a combination of 1H and 13C NMR, HSQC and HMBC experiments.

Synthesis and antimicrobial activities of 4-aryl-3,4-dihydrocoumarins and 4-arylcoumarins

A new series of 4-aryl-3,4-dihydrocoumarins and 4-arylcoumarins were synthesized by the reaction of substituted cinnamic acids and 3-arylpropiolic acid with the corresponding phenols. These compounds were evaluated for antibacterial activity in vitro. The

Efficient synthesis and biological evaluation of 4-arylcoumarin derivatives

Two bioactive natural 4-arylcoumarins, 5,7,4′-trimethoxy-4- phenylcoumarin (1a), 5,7-dimethoxy-4-phenylcoumarin (1b) and five closely related derivatives 1c-g were synthesized. In vitro evaluation with a catechol subunit for antioxidant and antimicrobial activity, these compounds using standard methods showed that compounds 1d, 1f displayed promise radical scavenging activity and 1f was found to be the most active one against Bacillus dysenteriae.

N-heterocyclic carbene derived Nickel-Pincer complexes: Efficient and applicable catalysts for Suzuki-Miyaura coupling reactions of aryl/alkenyl tosylates and mesylates

Catalytic activities of NHC-derived nickel-pincer complexes for the Suzuki-Miyaura coupling reactions of aryl/alkenyl to- sylates and mesylates are described. In the presence of a catalytic amount of nickelacycle 1a, a wide array of tosylates and mesylates reacted with several aryl- and alkenylboronic acids to afford the coupling products, generally in high yields. Fine tuning of the reaction conditions for each class of electrophiles was achieved only by choosing the appropriate reaction medium (DME for tosylates, dioxane for mesylates).

Short synthesis of cytotoxic 4-arylcoumarins

A short synthesis of cytotoxic 4-arylcoumarins via condensation of phenols with cinnamic acids in the presence of CF3COOH, followed by dehydrogenation with DDQ, is described. Copyright Taylor & Francis Group, LLC.
