Abstract
The organocatalytic asymmetric transfer hydrogenation of N-alkyl aryl imino esters for the direct synthesis of N-alkylated arylglycinate esters is reported. High yields and enantiomeric ratios were obtained, and tolerance to a diverse set of functional groups facilitated the preparation of more complex molecules as well as intermediates for active pharmaceuticals. A simple recycling protocol was developed for the Brønsted acid catalyst which could be reused through five cycles with no loss of activity or selectivity.

Abstract
Biocatalysis is currently employed to produce known substances more economically and for the synthesis of new compounds. Increased production or novel product synthesis can be achieved through the use of mutant organisms, tailored enzymes or novel combinations of enzymes in reactors. These complex biosyntheses, once only in the realm of the biopharmaceutical industry, have now been embraced by the food and textile industries and are finding geochemical and environmental applications. New uses are dictating novel methods of manufacture that utilize knowledge of systems level biology. Increased understanding of the functional interaction of proteins and protein-protein networks is also altering the practice of in vitro biosynthesis.

Abstract
Whereas the beta-lactam acylases are traditionally used for the hydrolytic processing of penicillin G and cephalosporin C, new and mutated acylases can be used for the hydrolysis of alternative fermentation products as well as for the synthesis of semisynthetic beta-lactam antibiotics. Three-dimensional structural analyses and site-directed mutagenesis studies have increased the understanding of the catalytic mechanism of these enzymes. The yield of hydrolysis and synthesis has been greatly improved by process design, including immobilization of the enzyme and the use of alternative reaction media. Significant advances have also been made in the resolution of racemic mixtures by means of stereoselective acylation/hydrolysis using beta-lactam acylases.
