experimental part, p. 26 - 28 (2011/04/26)
Two optically active heterocyclic imine ligands 3 (3a and 3b) have been synthesised for the iridium catalysed asymmetric transfer hydrogenation of 4-benzoylpyridine. 3b was characterised by single crystal X-ray diffraction analysis. The two ligands (3a an
One-pot diastereoselective synthesis of α-aminonitriles from aldehydes, chiral amines, and trimethylsilyl cyanide under solvent-free conditions

, p. 48 - 51 (2007/10/03)
Treatment of aliphatic and aromatic aldehydes with chiral amines and trimethylsilyl cyanide in the absence or in the presence of Lewis acids (including lithium perchlorate) under solvent-free conditions afforded the corresponding α-aminonitriles in good y
Facile synthesis of (S,S)-1,2-diacylamides and (S,S)-1,2-diamines with C2-symmetry

A series of chiral vicinal tertiary diacylamides with C2- symmetry was synthesized from (S)-α-phenylethylamine, different aromatic aldehydes, and oxalyl chloride. The diacylamides obtained were then reduced to afford chiral vicinal diamines wit
Asymmetric Catalyses, 14. Enantioselective Hydrosilylation of Prochiral Ketones with Rh- and Pt-Complexes of Optically Active N-Chelate Ligands
Brunner, Henri,Reiter, Barbara,Riepl, Georg
, p. 1330 - 1354 (2007/10/02)
N-chelate ligands with a lateral chiral center, which derive from optically active primary amines, amino acids, and amino acid derivatives, catalyze in Rh and Pt complexes the enantioselective hydrosilylation of acetophenone, benzyl methyl ketone, and tert-butyl methyl ketone with diphenyl- and 1-naphthylphenylsilane.The ketones are transformed into the corresponding silyl ethers which on hydrolysis yield the alcohols 1-phenylethanol, 1-phenyl-2-propanol and 3,3-dimethyl-2-butanol. 37 N ligands 1 - 37 with 2 (I) and K (XX) as well as 21 isolated complexes II - XIX and XXI - XXIII are tested.The best optical inductions exceed considerably those which were obtained with optically active phosphane containing catalysts used up to now.
