  1. 1. Engineered Yeast as Biocatalyst for Stereoselective reductions of Dicarbonyl Compounds

    Författare :Ted Johanson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chiral; screening; process optimisation; metabolic engineering; dicarbonyl; biocatalysis; yeast; bioreduction; Biotechnology; Bioteknik;

    Sammanfattning : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. LÄS MER

    Sammanfattning : Several ligands based upon 2-substituted bicyclic[2.2.2]octane-2,6-diols (BODOLs) were synthesized and evaluated in two catalytic reactions: I) the Ti(IV)-mediated catecholborane asymmetric reduction of prochiral ketones and II) as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes.
