Palladium-Catalyzed Asymmetric (2+3) Annulation of p-Quinone Methides with Trimethylenemethanes: Enantioselective Synthesis of Functionalized Chiral Spirocyclopentyl p-Dienones

A novel asymmetric catalytic (2+3) annulation of p-quinone methides with CN-substituted trimethylenemethane is described under palladium catalysis, providing an alternative approach for the enantioselective construction of highly functionalized chiral spirocyclopentyl p-dienones. Driven by the significant improvement in the reactivity and enantioselectivity, a novel type of non-C2-symmetric phosphoramidite ligand from the chirality-matched combination of (S)-BINOL and sterically demanding amine derived from l-hydroxyproline is evolved and explored for the protocol presented here.

A new organocatalytic concept for asymmetric -alkylation of aldehydes

The organocatalytic asymmetric -alkylation of aldehydes by 1,6-conjugated addition of enamines to p-quinone methides is described. Employing a newly developed class of chiral secondary amine catalysts,-diarylmethine-substituted aldehydes with two contiguo

Polystyrene-supported diarylprolinol ethers as highly efficient organocatalysts for Michael-type reactions

α,α-Diphenylprolinol methyl- and trimethylsilyl ethers anchored onto a polystyrene resin have been prepared by a copper-catalyzed azide-alkyne cycloadditions (CuAAC). The catalytic activity and enantioselectivity displayed by the O-trimethylsilyl derivati

NHC-Catalyzed intramolecular redox amidation for the synthesis of functionalized lactams

A very efficient NHC-catalyzed lactamization reaction is reported. For most cases, the ring expansion reaction proceeds to cleanly furnish five- and six-membered N-Ts and N-Bn lactams, without the need for further purification. Evidence is presented suggesting a dual role for the stoichiometric base: (1) deprotonation of the triazolium precatalyst and (2) activation of the nitrogen leaving group through hydrogen bonding.

Highly enantioselective synthesis of β-amino alcohols: A catalytic version

(Chemical Equation Presented) Highly enantioselective rearrangement of β-amino alcohols was realized by using a catalytic amount of trifluoroacetic anhydride.

Enantioselective diethylzinc addition to aromatic and aliphatic aldehydes using (3R,5R)-dihydroxypiperidine derivatives catalyst

A series of chiral (3R,5R)-dihydroxypiperidine derivatives 3a-f were conveniently prepared from trans-4-hydroxy-l-proline and applied to the catalytic enantioselective addition of diethylzinc to benzaldehyde and heptanal. Among them, 3d was found to show

Unusual diastereoselection in the synthesis of nine-membered ring lactams and conformation-controlled transannular reactions to generate optically active indolizidinones

The aza-Claisen rearrangement of vinylpyrrolidines 1 yielded almost exclusively the trans-3,8-disubstituted nine-membered ring lactams 2 (TBS = tBuMe2Si), independent of whether cis or trans isomers were used as starting materials. The conforma
