Asymmetric hydrolysis by lipases

Based on the recent impressive progress made on asymmetric hydrolysis, the design and bio-transformation of the optically active ethyl 2,2-difluoro-3-hydroxyoctanoate 78 and synthesis of optically active fluorinated [6]-gingerol derivatives are reported [82]. The following criteria were used in the search for a practical route to chiral ethyl 2,2-difluoro-3-hydroxyoctanoate with a high -value (1) the search of an additive to enhance the enantioselectivity of asymmetric hydrolysis by lipases, and (2) the modification of ethyl 2,2-difluoro-...
