Catalytic properties of commercially available lipases from Candida cylindracea, Rhizopus arrhizus, Aspergillus niger, Penicillium roqueforti, Geotrichum candidum, and porcine pancreas, and those of a crude lipase isolated from G. candidumwere studied. Esterification of the racemic cis- and trans-isomers of 2-(4-methoxymethoxybenzyl)-1-cyclohexanol in organic solvents and hydrolysis of the racemic cis- and trans-isomers of 2-(4-methoxymethoxybenzyl)-1-cyclohexyl acetates were investigated, and all existing enantiomers of 2-(4-methoxymethoxy-benzyl)-1-cyclohexanol were prepared, isolated, and characterized by their physicochemical properties. Alcohols2aand2band acetates4aand4bwere found to be the principle products of enzymemediated reactions. The optimum reaction conditions for the enzyme-mediated hydrolysis of1aand1band for the enzyme-mediated esterification of3aor3bwere found, when G. candidumwas used. We also compare the advantages and disadvantages of employing the appropriate enzymes. |
