Synthesis of Chiral Tetrahydrofurans and Pyrrolidines by Visible‐Light‐Mediated Deoxygenation
نویسندگان
چکیده
The synthesis of chiral tetrahydrofurans and pyrrolidines starting from 1,2-diols or β-amino alcohols, respectively, by visible-light-mediated deoxygenation is described. Easily accessible monoallylated/propargylated substrates were activated either as inexpensive ethyl oxalates or as recyclable 3,5-bis(trifluoromethyl)benzoates to generate alkyl radicals suitable for 5-exo-trig/5-exo-dig cyclizations under visible-light irradiation.

متن کاملPalladium-mediated annulation of vinyl aziridines with Michael acceptors: stereocontrolled synthesis of substituted pyrrolidines and its application in a formal synthesis of (-)-α-kainic acid.
route to vinyl epoxides and vinyl aziridines via chiral sulfur ylides, we were keen to develop their potential in synthesis further. It had been reported that palladium-catalyzed reactions of vinyl epoxides and aziridines with doubly activated Michael acceptors gave tetrahydrofurans and pyrrolidines in good yield but usually with poor stereocontrol. However, related reactions with singly activa...
متن کاملPalladium-Catalyzed Carboetherification and Carboamination Reactions of γ-Hydroxy- and γ-Aminoalkenes for the Synthesis of Tetrahydrofurans and Pyrrolidines.
Substituted tetrahydrofuran and pyrrolidine moieties are displayed in a wide range of interesting biologically active molecules. The Pd-catalyzed carboetherification or carboamination of γ-hydroxy- and γ-aminoalkenes is a powerful tool for the construction of these heterocycles, as it is convergent and can allow access to a variety of analogs from a single γ-hydroxy- or γ-aminoalkene starting m...
متن کاملDiastereoselective synthesis of CF3-substituted, epoxide-fused heterocycles with β-(trifluoromethyl)vinylsulfonium salts.
CF(3)-substituted vinyl diphenylsulfonium triflate is an effective annulation reagent for the formation of α-CF(3) substituted, epoxide-fused heterocycles (pyrrolidines, piperidines, and tetrahydrofurans). This simple method affords a variety of valuable heterocyclic building blocks in a highly diastereoselective manner (dr >20:1).
