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

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

   Abstract : 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. READ MORE

4. 2. Synthesis and evaluation of bicyclic 1,3-diols (BODOLs) as ligands for asymmetric catalysis

   Author : Ian Sarvary; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; yeast reductions; supramolecular chemistry; diethylzinc; computation; structure of Ti-diolates; diol ligands; titanates; asymmetric catalysis; asymmetric synthesis;

   Abstract : 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.
