A new type of microemulsion system (Aerosol‐OT, water, hexanol) was used to entrap an enzyme (α‐chymotrypsin) in a reverse micelle. N‐acetyl L ‐tyrosine ethyl ester can be solubilised in this medium to give N ‐acetyl L ‐tyrosine hexyl ester in a good yield (80%). This is the first report of a successful enzymatic transesterification in a micellar medium.
