3-((3,5-Bis(trifluoromethyl)phenyl)amino)-4-(((1R)-(6-methoxyquinolin-4-yl)(5-vinylquinuclidin-2-yl)methyl)amino)cyclobut-3-ene-1,2-dione (cas: 1256245-79-0) belongs to quinuclidine derivatives. Quinuclidine acts as a catalyst, a chemical building block and is used in organic synthesis. The reactions of quinuclidine compounds that lead to opening of the 1-azabi-cyclic system at the N-C and C-C bonds to give piperidine derivatives or, via subsequent rearrangements, derivatives of other heterocyclic systems, are correlated.Product Details of 1256245-79-0

Catalytic enantioselective cascade Michael/cyclization reaction of 3-isothiocyanato oxindoles with exocyclic α,β-unsaturated ketones en route to 3,2′-pyrrolidinyl bispirooxindoles was written by Kayal, Satavisha;Mukherjee, Santanu. And the article was included in Organic & Biomolecular Chemistry in 2016.Product Details of 1256245-79-0 This article mentions the following:

Cascade Michael/cyclization reactions between 3-isothiocyanato oxindoles and exocyclic α,β-unsaturated ketones are shown to proceed efficiently in the presence of a quinine-derived tertiary amino-squaramide catalyst and furnish 3,2′-pyrrolidinyl bispirooxindoles containing two spiro-quaternary and three contiguous stereocenters, e.g., I as a single diastereomer with excellent enantioselectivities (up to 99 : 1 er). In the experiment, the researchers used many compounds, for example, 3-((3,5-Bis(trifluoromethyl)phenyl)amino)-4-(((1R)-(6-methoxyquinolin-4-yl)(5-vinylquinuclidin-2-yl)methyl)amino)cyclobut-3-ene-1,2-dione (cas: 1256245-79-0Product Details of 1256245-79-0).
