Reference of 288-14-2, 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, 288-14-2, Isoxazole, introducing its new discovery.
Gold-catalyzed [4+3]- and [4+2]-annulations of 3-en-1-ynamides with isoxazoles: Via novel 6pi-electrocyclizations of 3-azahepta trienyl cations
New gold-catalyzed [4+3]-annulations of 3-en-1-ynamides with isoxazoles afford 4H-azepines efficiently; this process involves 6pi electrocyclizations of gold-stabilized 3-azaheptatrienyl cations. In the presence of Zn(OTf)2, the resulting 4H-azepines undergo skeletal rearrangement to furnish substituted pyridine derivatives. We subsequently develop new catalytic [4+2]-annulations between the same 3-en-1-ynamides and isoxazoles to deliver substituted pyridine products using Au(i)/Zn(ii) catalysts. This work reports the first success of the 6pi electrocyclizations of heptatrienyl cations that are unprecedented in literature reports.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 288-14-2. In my other articles, you can also check out more blogs about 288-14-2
