چکیده

Attractive carbocyclic structures are accessed via a highly regio- and enantioselective aminocatalytic γ-addition of cyclic enals to vinyl phosphonates followed by a one-pot intramolecular Horner-Wadsworth-Emmons reaction. It is also demonstrated that nitro olefins can act as electrophiles in a similar reaction concept, providing carbocycles in equally high stereoselectivity.

Development of a Unified Enantioselective, Convergent Synthetic Approach Toward the Furanobutenolide-Derived Polycyclic Norcembranoid Diterpenes: Asymmetric Formation of the Polycyclic Norditerpenoid Carbocyclic Core by Tandem Annulation Cascade.

An enantioselective and diastereoselective approach toward the synthesis of the tetracyclic scaffold of the furanobutenolide-derived polycyclic norditerpenoids is described. Focusing on synthetic efforts toward ineleganolide, the synthetic approach utilizes a palladium-catalyzed enantioselective allylic alkylation for the construction of the requisite chiral tertiary ether. A diastereoselective...

An organocatalytic domino Michael-alkylation reaction: highly enantioselective construction of spiro-cyclopentanoneoxindoles and tetronic acid scaffolds.

A new organocatalytic asymmetric domino Michael-alkylation reaction of methyleneindolinones and γ-halogenated-β-ketoesters is described. A variety of spiro-cyclopentanoneoxindoles were obtained in high yields (up to 96%), good diastereoselectivities (up to 12 : 1 dr) and excellent enantioselectivities (up to >99% ee) via α-alkylation. Interestingly, O-alkylated products with tetronic acid motif...

Asymmetric organocatalytic allylic alkylation of Reissert compounds: a facile access to chiral 1,1-disubstituted 1,2-dihydroisoquinolines.

The first asymmetric organocatalytic allylic alkylation of 1,2-dihydro-Reissert compounds and Morita-Baylis-Hillman (MBH) carbonates has been developed, which provided a novel protocol to construct enantioenriched functionalized 1,2-dihydroisoquinolines bearing vicinal quaternary and tertiary chiral centers at C-1 position (up to 94% ee, dr > 20 : 1).

Organocatalytic peroxy-asymmetric allylic alkylation.

The peroxy-asymmetric allylic alkylation of hydroperoxyalkanes with Morita-Baylis-Hillman carbonates was catalysed by modified cinchona alkaloids (up to 93% ee), from which chiral alpha-methylene-beta-hydroxy esters could be efficiently derived.
