The investigation consisted in application of three commercially available lipases (Novozyme 435, Lipozyme IM and non-immobilized powdered lipase from Candida antarctica), two ionic liquids (1-butyl-4-methylpyridinium chloride and 1,3-dimethylimidazolinium methyl sulfate), three modifications of the reaction conditions and two respective isomers of the racemic substrate (1 and 2), and resulted in our finding the appropriate conditions to get both of the products, stereoisomers of 2-(4-methoxybenzyl)cyclohexanol (3; 1S,2S) or (5; 1S,2R), and (in some cases) also the stereoisomers of the deracemized substrate (4; 1R,2R) or (6; 1R,2S) with high or acceptable enantiomeric purity. | URI: | https://hdl.handle.net/20.500.14279/27524 | ISSN: | 09574166 | DOI: | 10.1016/j.tetasy.2006.10.045 | Rights: | © Elsevier | Type: | Article | Affiliation: | National Technical University Of Athens Institute of Organic Chemistry and Biochemistry AS CR |
