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 derivatives are also widely utilized as homogeneous or heterogeneous catalysts in various asymmetric processes such as Morita–Baylis–Hillman reactions, Sharpless dihydroxylation reactions, and phase-transfer catalytic reactions. 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.Recommanded Product: 1256245-79-0

An unprecedented enantioselective oxa-Michael reaction of α-tertiary alcs. using cinchona-alkaloid-based chiral bifunctional squaramide catalysts is reported. An oxidative dearomatization of phenol followed by an enantioselective oxa-Michael addition sequence provided a broad array of chiral sterically hindered tetrahydrofurans and tetrahydropyrans attached to a cyclohexadienone moiety in spiro fashion. In general, good yields and excellent enantioselectivities (up to 99 %) were observed The chiral oxo-cycles obtained have easily been transformed into chromans without disturbing the enantioselectivity. 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: 1256245-79-0Recommanded Product: 1256245-79-0).
