Application of 538-58-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 538-58-9, 1,5-Diphenylpenta-1,4-dien-3-one, introducing its new discovery.
Enantioselective aza-Michael reaction of hydrazide to chalcones through the nonactivated amine moiety conjugated addition
The catalytic asymmetric aza-Michael reaction of benzoyl hydrazine toward chalcones through the nonactivated amine moiety conjugated addition was facilitated by the developed N,N?-dioxide-Sc(OTf)3 complex under mild conditions, affording the pharmacologically and synthetically useful products in moderate to high yields with up to 97% ee. The Royal Society of Chemistry.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 538-58-9! Application of 538-58-9
