Effect of chemical structure of benzofuran derivatives and reaction conditions on enantioselective properties of Aureobasidium pullulans microorganism contained in Boni Protect antifungal agent
Bioorganic asymmetric reduction of carbonyl compounds is one of the most important fundamental and practical reactions for producing chiral alcohols. The stereoselective bioreduction of prochiral ketones of benzofuran derivatives in the presence of yeast-like fungus Aureobasidium pullulans contained in the antifungal Boni Protect agent was studied. Biotransformations were carried out under moderate conditions in an aqueous and two-phase system and without multiplication of the bioreagent. Despite similar chemical structure, each of the used ketone has been reduced with varying efficiency and selectivity. One of the reasons for these results is the presence of a whole set of oxidoreductases in A. pullulans cells that are sensitive to the smallest changes in the structure of prochiral substrate. The unsymmetrical methyl ketones were biotransformed with the highest selectivity. Aureobasidium pullulans microorganism is less effective in the reduction of unsymmetrical halomethyl ketones. The presence of a heteroatom in the alkyl group significantly decreases the selectivity of the process. Finally, as a result of the preferred hydride ion transfer from the dihydropyridine ring of the cofactor to the carbonyl double bond on the re side, secondary alcohols of the S and R configuration were obtained with moderate to high enantioselectivity (55-99%).
