Enantioselective hydrogenation of activated ketones in the presence of Pt-Cinchona catalysts. Is the proton transfer concept valid?
Experimental evidences related to the proton transfer in the catalytic system Pt-Cinchona alkaloids for enantioselective hydrogenation of activated ketones were collected and analyzed. Both new and earlier results indicate that in aprotic media direct transfer of proton from platinum to the substrate with the involvement of quinuclidine nitrogen as a general rule can be questioned.
متن کاملOrganocatalytic asymmetric direct vinylogous Michael addition of α,β-unsaturated γ-butyrolactam to nitroolefins.
The first organocatalytic enantioselective direct vinylogous Michael reaction of α,β-unsaturated γ-butyrolactam to nitroolefins is developed using cinchona alkaloids as the catalysts. Both product enantiomers are accessible with moderate to good enantioselectivity.
متن کاملAsymmetric desymmetrization of meso-diols by C 2-symmetric chiral 4-pyrrolidinopyridines
In this work we developed C(2)-symmetric chiral nucleophilic catalysts which possess a pyrrolidinopyridine framework as a catalytic site. Some of these organocatalysts effectively promoted asymmetric desymmetrization of meso-diols via enantioselective acylation.
متن کاملRecent developments in the use of catalytic asymmetric ammonium enolates in chemical synthesis.
Catalytic enantioselective transformations of carbonyl compounds via enolates that comprise the enolization and bond-forming step have received considerable attention within the synthetic organic chemistry community. Many of these methods have exploited the versatile properties of asymmetric Lewis acid complexes that display basic and/or acidic properties and have successfully lead to the devel...
متن کاملElucidation of the active conformation of cinchona alkaloid catalyst and chemical mechanism of alcoholysis of meso anhydrides.
Complementary to enantioselective transformations of planar functionalities, catalytic desymmetrization of meso compounds is another fundamentally important strategy for asymmetric synthesis. However, experimentally established stereochemical models on how a chiral catalyst discriminates between two enantiotopic functional groups in the desymmetrization of a meso substrate are particularly lack...
