Abstract:A series of dihydroflavonol derivatives were synthesized by the reaction of 2'-hydroxyl chalcone derivatives with H 2 O 2 /(CH 3 CH 2 ) 2 NH system in anhydrous tetrahydrofuran under low temperature. The influences of reaction temperature, reaction solvents, the kinds and proportion of alkaline additive and oxidants on this reaction were investigated, and the optimal reaction conditions were determined. This method has the advantages of simple operation, mild conditions and convenient post-treatment. Besides, … Show more
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.
