  series of novel hybrid phosphorus ligands were designed and applied to the Rh-catalyzed enantioselective anti-Markovnikov hydroformylation of unfunctionalized 1,1-disubstituted alkenes. By employing the new catalyst, linear aldehydes with β-chirality can be prepared with high yields and enantioselectivities under mild conditions. Furthermore, catalyst loading as low as 0.05 mol % furnished the desired

• Asymmetric transfer hydrogenation in aqueous media catalyzed by resin-supported peptide having a polyleucine tether

  A resin-supported N-terminal prolyl peptide having a beta-turn motif and a polyleucine tether has been developed for the organocatalytic asymmetric transfer hydrogenation under aqueous conditions. Polyleucine accelerated the reaction in a highly enantioselective manner by providing a hydrophobic microenvironment around the prolyl residue. The investigation of catalyst structures indicates that the L-form of polyleucine is essential for both reaction efficiency and enantioselectivity. (c) 2009 Elsevier Ltd. All rights reserved.

  A resin-supported N-terminal prolyl peptide having a beta-turn motif and hydrophobic polyleucine chain effectively catalyzed the asymmetric transfer hydrogenation under aqueous conditions. The polyleucine tether provides a hydrophobic cavity in aqueous media that brought about a remarkable acceleration of the reaction. In addition, the polyleucine chain also turned out to be essential for high enantioselectivity.
