Synthesis of Dichalcone compounds and Study biological activity

Abstract

, In this research some new chalcon were prepared Synthesis new derivatives of dichalcones by condensing1-[4-(Ethyl-nonyl)-phenyl]-ethanone with appropriate aldehyde preparation two methods were used to the derivatives of dichalcones , there are condisation , and irridation of microwaves compounds (1-5) Synthesis of new chalcones derivatives containing on the epoxide oxirane ring [ compounds (6-10)] , others contained bromine compounds (11-15) The prepared compounds were identefical uving IR , UV and Nuclear Magnatic Resonance spectra for some of them . The biological activity of the prepared compounds was invejtigated and the prepared compound showed agood inhibition effect aginest some types of micro organisms .
