Phosphine-Catalyzed [3 + 2] Annulation of Morita-Baylis-Hillman Carbonates with Isoxazole-Based Alkenes

A phosphine-catalyzed [3 + 2] annulation of Morita-Baylis-Hillman (MBH) carbonates with 3-methyl-4-nitro-5-styrylisoxazoles has been developed to afford various multifunctional isoxazoles in moderate to good yields with moderate to excellent diastereoselectivities. With a spirocyclic chiral phosphine as the catalyst, up to 89% ee was obtained.

Phosphine-catalyzed [3+2] cycloaddition of Morita—Baylis—Hillman carbonates to isothiocyanates in the synthesis of adamantane-containing trisubstituted aminothiophenes

An addition of the Morita—Baylis—Hillman (MBH) carbonates to adamantane-containing isothiocyanates was studied. The MBH carbonates react with 1-(4-isothiocyanatophenyl)-adamantane in the presence of triphenylphosphine to give 5-aryl-substituted adamantane

Synthesis of β-Lactams via Enantioselective Allylation of Anilines with Morita-Baylis-Hillman Carbonates

Enantioenriched β-lactams are accessed via enantioselective allylation of anilines with Morita-Baylis-Hillman carbonates followed by a base-promoted cyclization. The resulting 3-methyleneazetidin-2-ones are amenable to diastereoselective functionalization

Enantioselective dearomative [3+2] cycloaddition of 2-nitrobenzofurans with aldehyde-derived Morita-Baylis-Hillman carbonates

The phosphine-catalyzed asymmetric dearomative [3+2] cycloaddition of 2-nitrobenzofurans with aldehyde-derived Morita-Baylis-Hillman (MBH) carbonates or allenoate was developed. The reaction with MBH carbonates resulted in a series of cyclopentabenzofurans containing three contiguous stereocenters with good to high yields, diastereoselectivities and enantioselectivities. The use of allenoate also gave the target product with moderate enantioselectivity.

Direct Synthesis of Dihydropyrrolo[2,1-a]Isoquinolines through FeCl3 Promoted Oxidative Aromatization

We have developed a straightforward FeCl3 promoted synthesis of dihydropyrrolo[2,1-a]isoquinolines through formal (3+2) cycloaddition/oxidative aromatization cascade of dihydroisoquinoline with Morita-Baylis-Hillman carbonates (up to 96% yield)

Effective and diastereoselective preparation of dispiro[cyclopent-3′-ene]bisoxindoles: Via novel [3 + 2] annulation of isoindigos and MBH carbonates

A novel and diastereoselective [3 + 2] annulation of isoindigos and Morita-Baylis-Hillman carbonates has been developed for the highly efficient and one-step preparation of highly steric dispiro[cyclopent-3′-ene]bisoxindoles with two all-carbon quaternary

Umpolung of o-Hydroxyaryl Azomethine Ylides: Entry to Functionalized ?-Aminobutyric Acid under Phosphine Catalysis

A phosphine-catalyzed reaction between o-hydroxyaryl azomethine ylides and MBH carbonates provides access to highly functionalized ?-aminobutyric acid derivatives in moderate to good yields. Mechanistically, the reaction involves a phosphine-catalyzed tandem SN2′/2-aza-Cope rearrangement/intramolecular addition process.

Synthesis of Chiral α-Trifluoromethylamines with 2,2,2-Trifluoroethylamine as a "building Block"

The β-isocupreidine, a cinchonine derived alkaloid, catalyzed asymmetric SN2′-SN2′ reaction between N-2,2,2-trifluoroethylisatin ketimines and MBH type carbonates was realized in a simple and efficient way. A series of chiral α-trifl

Catalytic asymmetric one-pot synthesis of α-methylene-γ-lactams

An organocatalytic enantioselective synthesis of α-methylene-γ- lactams has been developed. The reaction between protected 2-aminomalonates and Morita-Baylis-Hillman carbonates is catalyzed by chiral Lewis bases to afford the corresponding lactams in exce

Organocatalytic enantioselective allylic alkylation of MBH carbonates with β-keto esters

The highly stereoselective allylic alkylation of Morita-Baylis-Hillman carbonates with β-ketoesters catalysed by β-ICD is described. The corresponding products containing two adjacent quaternary and tertiary carbon centers were obtained in good yields with high diastereoselectivity (up to 10 : 1 dr) and enantioselectivity (up to 95% ee).
