Maleimide as an efficient nucleophilic partner in the aza-Morita-Baylis-Hillman reaction: synthesis of chiral 3-substituted-3-aminooxindoles.
نویسندگان
چکیده
A highly enantioselective Morita-Baylis-Hillman reaction of maleimides with isatin derived ketimines has been developed to obtain enantiomerically enriched 3-substituted-3-aminooxindoles using β-isocupreidine as an organocatalyst. Maleimide acting as a nucleophile provides products with up to 99% ee.

Enantioselective, organocatalytic Morita-Baylis-Hillman and Aza-Morita-Baylis-Hillman reactions: stereochemical issues.
Conscious of the importance that stereochemical issues may have on the design of efficient organocatalyts for both Morita-Baylis-Hillman and aza-Morita-Baylis-Hillman reaction we have analyzed them in this minireview. The so-called standard reactions involve "naked" enolates which therefore should lead to the syn adducts as the major products, irrespective of the E, Z stereochemistry of the eno...
متن کاملChiral phosphine Lewis bases in catalytic, asymmetric aza-Morita–Baylis–Hillman reaction*
In the aza-Morita–Baylis–Hillman reaction of N-sulfonated imines with methyl vinyl ketone (MVK) promoted by chiral phosphine Lewis base: (R)-2'-diphenylphosphanyl[1,1']binaphthalenyl-2-ol (LB1) (10 mol %), the aza-Morita–Baylis–Hillman adducts were obtained in good yields with high ee (70–94 % ee) at –30 °C in THF. The scope and limitations of this reaction have been disclosed.

This review describes our recent efforts in the development of acid-base organocatalysts, (S)-3-(N-isopropyl-N-3-pyridinylaminomethyl) BINOL (6a) and (S)-3-[2-(diphenylphosphino)phenyl] BINOL (13a), with dual activation mechanism for the aza-Morita-Baylis-Hillman (aza-MBH) reaction. In these catalysts, chiral Brønsted acid units are connected with a Lewis base unit via a spacer. The acid-base m...

An efficient organocatalytic asymmetric [3 + 2] cycloaddition reaction between 3-substituted methylenebenzofuranone derivatives and diverse Morita-Baylis-Hillman carbonates to provide complex polysubstituted spirocyclopentenebenzofuranone scaffolds in a single step is reported. C2-symmetric phospholanes were efficient nucleophilic catalysts of this transformation under mild conditions, providin...
متن کاملEnantioselective aza-Morita-Baylis-Hillman reactions of acrylonitrile catalyzed by palladium(II) pincer complexes having C2-symmetric chiral bis(imidazoline) ligands.
Significance: This paper describes the palladiumcatalyzed enantioselective aza-Morita–Baylis–Hillman reaction of acrylonitriles with imines. The bulky pincer ligand enabled the synthesis of enantioenriched α-methylene-β-aminonitriles in high yield. Comment: The palladium–pincer complex preferably activates acrylonitrile, even in the presence of ethyl acrylate. The palladium ketenimide is a key ...
