Das durch Kondensation von Dichlorben‐ zoylpropionsäure (I) mit den aromatischen Aldehyden (II) zugängliche Arylidenfuranon (III) hydrolysiert alkalisch zu den Phenacylzimtsäuren (IV), mit primären aromatischen Aminen (VI) lassen sich die Arylidenpyrrolidone (V) darstellen, mit primären aliphatischen Aminen (VII) werden die Phenacylzimtsäureamide (VIII) gebildet.
A series of 1,2,4-triazole scaffold containing alkoxy moiety 4a-b and 9a-e was synthesized by stirring compounds 3a-b or 8a-d at room temperature with different acid chlorides including 4-methoxy benzoyl chloride or 3,4,5-trimethoxybenzoyl chloride. The structure of the prepared compounds was confirmed using different spectroscopic techniques such as IR, 1 H NMR, 13 C NMR, Mass spectra and high resolution mass or elemental analysis. The synthesized compounds examined for their antioxidant activity using DPPH radical scavenging activity. Results indicated that most of the tested compounds exhibited moderate antioxidant activity. Compound 9b exhibited remarkable antioxidant activity with DPPH radical scavenging rate of 49.4 % compared to trolox as a reference antioxidant agent at 10µM concentration.
R 0502 0‐Phenylacetylbenzoesäure (I) kondensiert mit aromatischen Aldehyden (II) R 0063 zu den Chalcon‐Derivaten (III), von denen (IIIa) in äthanolischer Salzsäure R 0590 ins Hydroxylacton (IV) verwandelt wird.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
