A recombinant isoenzyme of pig liver esterase was used for the highly enantioselective desymmetrization of dimethyl cyclohex-4-ene-cis-1,2- dicarboxylate. The selected recombinant esterase showed a significant advantage in enantioselectivity over the comm
Chemoenzymatic Sequential Multistep One-Pot Reaction for the Synthesis of (1S,2R)-1-(Methoxycarbonyl)cyclohex-4-ene-2-carboxylic Acid with Recombinant Pig Liver Esterase

In this work, the development of a chemoenzymatic process for the production of (1S,2R)-1-(methoxycarbonyl)cyclohex-4-ene-2-carboxylic acid by ECS-PLE06 (recombinant pig liver esterase) is presented. Herein an optimized esterification protocol, starting f
Simple and highly enantioselective nonenzymatic ring opening of cyclic prochiral anhydrides

, p. 195 - 196 (1999)
A convenient highly enantioselective methanolysis of cyclic meso- anhydrides only requires one equivalent cinchona alkaloid and low temperature. Both enantiomers can be easily obtained with up to 98% ee by using either quinine or quinidine.
Asymmetric hydrolysis of a meso-diester using pig liver esterase immobilised in hollow fibre ultrafiltration membrane
Sousa, Helena A.,Crespo, Joao G.,Afonso, Carlos A.M.
, p. 929 - 934 (2000)
Pig liver esterase (PLE) was physically immobilised in a polysulphone ultrafiltration hollow fibre membrane reactor and used for the repetitive batch two-phase hydrolysis and separation, on a multigram scale, of the meso-diester dimethyl cis-cycloxex-4-en
Ionic Liquid Gels: Supramolecular Reaction Media for the Alcoholysis of Anhydrides
Rizzo, Carla,Mandoli, Alessandro,Marullo, Salvatore,D'Anna, Francesca

The search of new enantioselective catalysts, able to promote synthetically useful organic reactions with high levels of asymmetric induction, should be associated with the attention to the suitable reaction medium able to achieve the best efficiency in c

The asymmetric nucleophilic catalysis by fluoride ions at a carbon-based electrophile has been demonstrated for the first time. Using a library of ad hoc designed bifunctional phase-transfer catalysts in which both the anion and the cation are directly involved in the reaction, the desymmetrisation of meso-succinic and -glutaric anhydrides is possible.19F NMR spectroscopic studies support the intermediacy of an acyl fluoride intermediate.
