Organogels: A new system for lipases immobilization and its application in organic synthesis.

Lipases have been immobilized in microemulsion-based organogels (MBG's) and successfully utilized for the enantioselective esterification, diesterification and transesterification reactions, in organic solvents at 25 degrees C. This methodology Is described as a new alternative for the use of enzymes in organic solvents, High enzymic stability has been observed, We have also used this methodology for the successful resolution of chiral secondary alcohols, This is a convenient way of using this catalyst in organic solvents which employs small amounts of the enzyme (250 mu g/mL).
