    Notes: Die mikrobielle asymmetrische Reduktion von Ketonen wird sehr oft zur Herstellung chiraler Alkohole benutzt. Dieser Fortschrittsbericht beschäftigt sich mit den Gesetzmäßigkeiten, die der Enantioselektivität von Enzymen und intakten Zellen zugrundeliegen. Es werden Strategien zur Steuerung des stereochemischen Verlaufs mikrobieller Reduktionen und die Beziehung zwischen Substratstruktur und Enantioselektivität diskutiert.

    Notes: Die enantioselektive Biokatalyse in nicht-wäßrigen Medien gewinnt in der präparativen Chemie zunehmend an Bedeutung. Dieser Beitrag beschreibt a) die generellen katalytischen Eigenschaften von Enzymen in nicht-wäßriger Umgebung, b) die grundlegenden Prinzipien der Herstellung optisch aktiver Carbonsäuren und Alkohole durch Lipase-katalysierte enantioselektive Veresterungen und Umesterungen in organischen Medien, c) die Bestimmung kinetischer und thermodynamischer Parameter und d) die quantitative Analyse von veröffentlichten Daten.

    Notes: Microbial asymmetric reduction of ketones is a method widely used for the preparation of chiral alcohols. The present progress report deals with the basic concepts that govern enantioselectivity of enzymes and intact cells. Strategies to control the stereochemical course of microbial reductions of carbonyl compounds and the relationship of substrate structure to enantioselectivity are considered.

    Notes: Enantioselective biocatalysis in nonaqueous media is becoming increasingly important in preparative synthetic chemistry. This article discusses (1) the general catalytic properties of enzymes in nonaqueous environments, (2) the basic principles that govern lipase-catalyzed enantioselective esterification and transesterification reactions in organic media for the preparation of optically active acids and alcohols, (3) the determination of kinetic and thermodynamic parameters, and (4) the quantitative analysis of published data.
