Enhancements of enantio and diastereoselectivities in reduction of (Z)-3-halo-4-phenyl-3-buten-2-one mediated by microorganisms in ionic liquid/water biphasic system
摘要:
Reductions of (Z)-C6H5CH=CXC(=O)CH3 (X=Cl, Br) mediated by Saccharomyces cerevisiae, Candida albicans, Rhodotorula glutinis, Geotrichum candidum and Micrococcus luteus gave the corresponding halohydrins through consecutive reduction reactions of C=C and C=O bonds. In general, the reactions performed in the biphasic system water/[(bmim)PF6] gave better diastereoselectivity and enantioselectivity than in pure water. (C) 2012 Elsevier B.V. All rights reserved.
