, p. 466 - 470 (2009)
Novel Rh(iii) and Ir(iii) complexes of a chiral diamine ligand have been synthesised and structurally characterised. Both complexes were formed as a single diastereomeric species with a single configuration at nitrogen. Ir complexes of the chiral diamine
Chiral Discrimination towards Racemic Alcohols through Host/Guest Clathrate Inclusion with Axially Chiral 1,1'-Binaphthyl-2,2'-dicarboxylic Acid

, p. 405 - 406 (1988)
Axially chiral 1,1'-binaphthyl-2,2'-dicarboxylic acid (1) was successfully utilised as a new type of chiral host molecule soluble in aqueous alkaline solution; 1-phenylalkan-1-ols were optically resolved by means of chiral host/guest chlatrate inclusion giving optical purities ranging from 18 to 90percent enantiomeric excess (e.e.) depending on the alkyl group.
Alkylmetal Asymmetric Reduction. 13. A Sterically Crowded Chiral Organoaluminum Compound as a Reducing Agent of Ketones

, p. 310 - 313 (1984)
Optically active carbinols were obtained by reducing the corresponding ketones with heptan-2-yl>methyl>aluminum dichloride.The reactions, which have been carried out at room temperature, are fast and afforded the carbinols in good chemical and optical yields.The extent of the enantioselectivity, along with the stereochemistry of the process, was found to depend on the structure of the ketone employed.The overall results indicated that the present reducing method may be a convenient route to obtain secondary alcohols of high enantiomeric purity under mild conditions.
