Development of Guanidine-Bisurea Bifunctional Organocatalysts with a Chiral Pyrrolidine Moiety and Application to ?-Hydroxylation of Tetralone-Derived ?-Keto Esters.

Project description:Novel guanidine-bisurea bifunctional organocatalysts 5 bearing a chiral pyrrolidine moiety on guanidine were designed with the guidance of DFT calculations. The resulting organocatalysts 5 were examined for ?-hydroxylation of tetralone-derived ?-keto esters, and good selectivity was obtained with 5j bearing a methoxymethyl ether-containing chiral pyrrolidine moiety.

Asymmetric Electrophilic Difluoromethylthiolation of Indanone-Based ?-Keto Esters Using Difluoromethanesulfonyl Hypervalent Iodonium Ylides.

Project description:The first electrophilic diastereoselective direct introduction of the difluoromethylthio group is described. We used a chiral auxiliary-based approach to illustrate the versatility of our recently developed difluoromethanesulfonyl hypervalent iodonium ylide reagents for the difluoromethylthiolation of indanone-based ?-keto esters. Chiral SCF?H-featuring compounds were obtained in up to 93% ee value.

Dynamic kinetic asymmetric cross-benzoin additions of ?-stereogenic ?-keto esters.

Project description:The dynamic kinetic resolution of ?-halo ?-keto esters via an asymmetric cross-benzoin reaction is described. A chiral N-heterocyclic carbene catalyzes the umpolung addition of aldehydes to racemic ?-keto esters. The resulting fully substituted ?-halo glycolic ester products are obtained with high levels of enantio- and diastereocontrol. The high chemoselectivity observed is a result of greater electrophilicity of the ?-keto ester toward the Breslow intermediate. The reaction products are shown to undergo highly diastereoselective substrate-controlled reduction to give highly functionalized stereotriads.

Asymmetric synthesis of anti-?-amino-?-hydroxy esters via dynamic kinetic resolution of ?-amino-?-keto esters.

Project description:A method for the asymmetric synthesis of enantioenriched anti-?-hydroxy-?-amino acid derivatives by enantioconvergent reduction of the corresponding racemic ?-keto esters is presented. The requisite ?-keto esters are prepared via Mannich addition of ethyl diazoacetate to imines followed by oxidation of the diazo group with Oxone. Implementation of a recently developed dynamic kinetic resolution of ?-substituted-?-keto esters via Ru(II)-catalyzed asymmetric transfer hydrogenation provides the title motif in routinely high diastereo- and enantioselectivity.

Highly functionalized 1,2-diamino compounds through reductive amination of amino acid-derived ?-keto esters.

Project description:1,2-Diamine derivatives are valuable building blocks to heterocyclic compounds and important precursors of biologically relevant compounds. In this respect, amino acid-derived ?-keto esters are a suitable starting point for the synthesis of ?,?-diamino ester derivatives through a two-step reductive amination procedure with either simple amines or ?-amino esters. AcOH and NaBH(3)CN are the additive and reducing agents of choice. The stereoselectivity of the reaction is still an issue, due to the slow imine-enamine equilibria through which the reaction occurs, affording mixtures of diastereoisomers that can be chromatographically separated. Transformation of the ?,?-diamino esters into pyrrolidinone derivatives allows the configuration assignment of the linear compounds, and constitutes an example of their potential application in the generation of molecular diversity.

Dynamic kinetic resolution of ?-keto esters via asymmetric transfer hydrogenation.

Project description:The dynamic kinetic resolution of ?-aryl ?-keto esters has been accomplished using a newly designed (arene)RuCl(monosulfonamide) transfer hydrogenation catalyst. This dynamic process generates three contiguous stereocenters with remarkable diastereoselectivity through a reduction/lactonization sequence. The resulting enantioenriched, densely functionalized ?-butyrolactones are of high synthetic utility, as highlighted by several secondary derivatizations.

Asymmetric allylic alkylation of Morita-Baylis-Hillman carbonates with ?-fluoro-?-keto esters.

Project description:In the presence of a commercially available Cinchona alkaloid as catalyst, the asymmetric allylic alkylation of Morita-Baylis-Hillman carbonates, with ?-fluoro-?-keto esters as nucleophiles, have been successfully developed. A series of important fluorinated adducts, with chiral quaternary carbon centres containing a fluorine atom, was achieved in good yields (up to 93%), with good to excellent enantioselectivities (up to 96% ee) and moderate diastereoselectivities (up to 4:1 dr).

Asymmetric ?-Chlorination of ?-Keto Esters Using Hypervalent Iodine-Based Cl-Transfer Reagents in Combination with Cinchona Alkaloid Catalysts

Project description:We herein report an unprecedented strategy for the asymmetric ?-chlorination of ?-keto esters with hypervalent iodine-based Cl-transfer reagents using simple Cinchona alkaloid catalysts. Our investigations support an ?-chlorination mechanism where the Cinchona species serves as a nucleophilic catalyst by reacting with the chlorinating agent to generate a chiral electrophilic Cl-transfer reagent in situ. Using at least 20 mol-% of the alkaloid catalyst allows for good yields and enantioselectivities for a variety of different ?-keto esters-under operationally simple conditions.
