So it is now with asymmetric catalysis, a field which promises to change profoundly the strategic thinking of synthetic chemists. As this Report will show, reagents which can induce catalytic enantiocontrol of chemical transformations could represent

Moreover, the turnover rates tend to be high, the chemical yields are usually quantitative and many of the hydrogenations can be carried out under ambient conditions. A simplified version of the catalytic cycle is given below (Figure 2.1), the details are discussed later.

Matthew O. Jackson on Hugo F. Sonnenschein,n Research of the University of Osaka. By careful evaluation of various parameters, such as origin of the nickel metal, the nature of chiral modifier and mode of modification, and pressure, temperature, and pH of the reduction, they have achieved steady progress in improving ee values, from 3–5% (19

David G. Pearce on Hugo F. Sonnenschein,eactions. Whereas many enzymes have been used, it is those enzyme systems that possess broad substrate specificities and high enantioselectivities that are best suited for asymmetric catalysis. Either isolated enzymes or intact microorganisms can be used. Since both processes are enzymic in the fina

William Novshek on Hugo F. Sonnenschein,cally pure compounds for the pharmaceutical industry is no longer a matter of convenience, it is a matter of law. The classic example of thalidomide has not gone unnoticed; the S-enantiomer causes malformations, the R-enantiomer does not. The racemic mixture was sold. There are numerous, less tragic
