Asymmetric construction of spirocyclohexanonerhodanines catalyzed by simple diamine derived from chiral tert-leucine.
نویسندگان
چکیده
A diamine-catalyzed asymmetric tandem reaction between α,β-unsaturated ketones and rhodanine derivatives has been developed to synthesize various spirocyclic compounds with high stereoselectivities (up to 99% ee and >20:1 dr). The products obtained contain two pharmaceutically relevant features: the biologically active rhodanine moiety embedded in a spirocyclic unit.

New auxiliaries for copper-catalyzed asymmetric Michael reactions: generation of quaternary stereocenters at room temperature.
Dialkyl amides of L-valine, L-isoleucine, and L-tert-leucine (2) are excellent chiral auxiliaries for the construction of quaternary stereocenters at ambient temperature. Enaminoesters 3, prepared from these auxiliaries 2 and Michael donors 1, undergo a copper-catalyzed asymmetric Michael reaction with methyl vinyl ketone (MVK, 4) to afford products 5 in 70-90% yield and 90-99% ee (enantiomeric...
متن کاملEnantioselective dearomatization of isoquinolines by anion-binding catalysis en route to cyclic α-aminophosphonates.
An enantioselective dearomatization of isoquinolines has been developed using chiral anion-binding catalysis. This transformation, catalyzed by a simple and easy to prepare tert-leucine-based thiourea derivative, makes use of silyl phosphite as a nucleophile and generates cyclic α-aminophosphonates. This is the first time asymmetric anion-binding catalysis has been applied to the synthesis of α...
متن کاملL-tert-Leucine-Derived AmidPhos–Silver(I) Chiral Complexes for the Asymmetric [3+2] Cycloaddition of Azomethine Ylides
The L-tert-leucine-derived AmidPhos/silver(I) catalytic system has been developed for the asymmetric [3+2] cycloaddition of azomethine ylides with electronic-deficient alkenes with or without Et3N. Under optimal conditions, highly functionalized endo-4-pyrrolidines were obtained with modest to high yields (up to 99% yield) and enantioselectivities (up to 98% ee).

Asymmetric Michael addition of 1-acetylindolin-3-ones to β,γ-unsaturated α-ketoesters was investigated for the synthesis of chiral indolin-3-ones with two adjacent tertiary stereogenic centers. Under the catalysis of a chiral bifunctional squaramide derived from l-tert-leucine, a wide range of 1-acetylindolin-3-ones and β,γ-unsaturated α-ketoesters were well-tolerated in this transformation to ...

One novel type of chiral olefin/sulfinimide hybrid ligands has been developed through a simple one-step condensation of α,β-unsaturated ketones with tert-butanesulfinamide and utilized successfully for rhodium-catalyzed asymmetric conjugated additions to furnish the desired adducts in high yields with excellent ee's.
