| 英文摘要 | The lipase-catalyzed enantioselective transesterification of racemic secondary alcohols was studied using vinyl acetate as acyl donor in two imidazolium-based ionic liquids vs. hexane (scheme), both in the absence and presence of catalytic amounts of organic bases such as triethylamine (et3n) or pyridine. the organic bases generally enhanced both the rate and enantioselectivity of the reaction. further, the system 1-butyl-3-methyl-1h-imidazolium hexafluorophosphate/candida antarctica lipase b ([bmim][pf6]/ calb) could be readily recycled four times without significant loss in activity or enantioselectivity (table 4). |
