Asynthesis of four pyridinium perchlorate compounds have been prepared from reaction one mole pyrylium salt (product already) with one mole cysteine in room temp. and diagnosed spectrally (FT-IR., 1 H-NMR) in addition to the accurate quantitative elemental analysis. Asynthesis of sixteen Thiopyranpyridinium perchlorate compounds from reaction one mole from pyridinium compounds produced with one mole pyrylium salt (product already) under zero temp. very good yields that were diagnosed spectrally (FT-IR., 1 H-NMR) in addition to the accurate quantitative elemental analysis.
A series of novel Azachalcone compounds were prepared by the reaction of 3acetyl pyridine with different aromatic aldehyd . Azachalcone was reacted with thiourea to give good yields of thiazines , all the new compounds were characterized by I.R, U.V and TLC. Also the Biological Activities of these compounds against anti bacteril and anti fungal were evaluated . some of these compounds gave good activity.
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.
