alpha,alpha-Diphenyl-L-prolinol derivatives with para-bromo substituants in either one or both of the phenyl rings are easily bound to crosslinked polystyrene beads containing phenylboronic acid residues by Suzuki couplings. By using extended reaction periods boronic acid residues that do not take part in the couplings are simply lost by hydrolysis. The polymer-supported (PS) alpha,alpha-diphenyl-L-prolinols were used to catalyse reductions of several prochiral ketones with borane in tetrahydrofuran at 22 C. The expected secondary alcohols were obtained in high chemical yields and ees were generally in the range 79-97 %. One PS catalyst was recycled 14 times without loss of stereochemical performance.

Novel bifunctional chiral squaramide-amine organocatalysts have been developed by rational combination of pyrrolidine and a cinchona alkaloid. The catalysts promoted the enantioselective Michael addition of both mono-and diketones to a broad range of nitroalkenes providing the corresponding products in moderate to high yields with excellent enantioselectivities and diastereoselectivities (up to 96% yield, 96% ee, 98:2 dr) under mild conditions. These results demonstrate that the assembly of two chiral privileged skeletons, pyrrolidine and cinchonine with a squaramide linker is a useful strategy to reach a wider substrate scope, high reaction efficiency and enantioselectivity. The match of the chiralities between two backbones embedded in the catalysts is also critical for improving enantioselectivity. ARKAT-USA, Inc.

Effect of ligand structure on the zinc-catalyzed Henry reaction. Asymmetric syntheses of (-)-denopamine and (-)-arbutamine

(Matrix presented) Syntheses of variously modified ligands for the dinuclear zinc catalysts for the asymmetric aldol and nitroaldol (Henry) reactions are reported. Catalytic enantioselective nitroaldol reactions promoted by these modified ligands led to efficient syntheses of the beta-preceptor agonists (-)-denopamine and (-)-arbutamine.

In search of diamine analogs of the alpha,alpha-diphenyl prolinol privileged chiral organocatalyst. Synthesis of diamine derivatives of alpha,alpha-diphenyl-(S)-prolinol and their application as organocatalysts in the asymmetric Michael and Mannich reactions

This paper describes improved reaction conditions for the substitution of the hydroxyl group in (S)-diphenyl(pyrrolidin-2-yl)methanol by the azide group, which was then reduced to the diamine derivative. We examined two protecting groups (N-Bn and N-Boc) on the pyrrolidine nitrogen in order to functionalize the primary amino group into various amide, alkylated amine, sulfonamide, thiourea and triazole derivatives. Notably, carefully controlled conditions were required to generate the desired derivatives from the sterically hindered benzhydrylamine moiety. Unexpectedly, upon removal of the N-protecting group in derivatives containing electrophilic polar double bonds (C=S, C=O) cyclization took place, affording products such as amidines. The target compounds were evaluated as bifunctional organocatalysts in the asymmetric Michael and Mannich addition reactions. (S)-2-(Azidodiphenylmethyl)pyrrolidine (S)-7 was identified as the most efficient organocatalyst among the various diamine derivatives of alpha,alpha-diphenyl-(S)-prolinol prepared in this work.

Highly Enantioselective Epoxidation of alpha,beta-Unsaturated Ketones Catalyzed by Rare-Earth Amides [(Me3Si)2N]3RE(mu-Cl)Li(THF)3 with Phenoxy-Functionalized Chiral Prolinols

A simple and efficient catalytic enantioselective epoxidation of alpha,beta-unsaturated ketones has been successfully developed, which was catalyzed by rare-earth metal amides [(Me3Si)2N]3RE(mu-Cl)Li(THF)3 (RE = Yb (1), La (2), Sm (3), Y (4), Lu (5)) in the presence of phenoxy-functionalized chiral prolinols at room temperature using tert-butylhydroperoxide (TBHP) as the oxidant. The combination of an Yb-based amide 1 and a chiral proligand (S)-2,4-di-tert-butyl-6-((2-(hydroxydiphenylmethyl)pyrrolidin-1-yl)methyl)phenol) performed very well, and both the yields and the enantiomeric excess of the chiral epoxides reached up to 99% and 99% ee.
