Proline-based reduced dipeptides as recyclable and highly enantioselective organocatalysts for asymmetric Michael addition.
A series of novel proline-based reduced dipeptides was developed and evaluated for a direct Michael addition of ketones and aldehydes to nitroalkenes. Excellent yields (up to 95%), diastereoselectivities (up to 98% dr) and enantioselectivities (up to 98% ee) were achieved in the presence of 5 mol% catalyst without any additional additives at room temperature.
متن کاملChiral amine-thioureas bearing multiple hydrogen bonding donors: highly efficient organocatalysts for asymmetric Michael addition of acetylacetone to nitroolefins.
New bifunctional organocatalysts amine-thioureas bearing multiple hydrogen bonding donors were synthesized and applied in catalytic asymmetric Michael addition of acetylacetone to aryl and alkyl nitroolefins. Multiple hydrogen bonding donors play a significant role in accelerating reactions, improving yields and enantioselectivities.
متن کاملPhosphine-boronates: efficient bifunctional organocatalysts for Michael addition.
Phosphine-boronates R(2)P(o-C(6)H(4))B(OR')(2) have been evaluated as bifunctional organocatalysts for the Michael addition of malonate pronucleophiles to methylvinylketone. The presence of the Lewis acidic boron center adjacent to phosphorus significantly improves catalytic performance. Isolation and complete characterization of a key intermediate, namely a β-phosphonium enolate, substantiate ...
متن کاملSupported bifunctional thioureas as recoverable and reusable catalysts for enantioselective nitro-Michael reactions
The catalytic activity of different supported bifunctional thioureas on sulfonylpolystyrene resins has been studied in the nitro-Michael addition of different nucleophiles to trans-β-nitrostyrene derivatives. The activity of the catalysts depends on the length of the tether linking the chiral thiourea to the polymer. The best results were obtained with the thiourea derived from (L)-valine and 1...
متن کاملChiral bifunctional ferrocenylphosphine catalyzed highly enantioselective [3 + 2] cycloaddition reaction.
A series of air-stable ferrocenylphosphines LB1-LB8 were designed and prepared in high yields. (R,SFc)-ferrocenylphosphine LB5 was found to efficiently promote the asymmetric [3 + 2] cycloaddition of Morita-Baylis-Hillman carbonates with maleimides to afford the corresponding bicyclic imides with 84-99% ee and 67-99% yield. Interestingly, the configuration of these products was contrary to thos...
