Chemical versus enzymatic catalysis for the regioselective synthesis of sucrose esters of fatty acids

摘要

In this work we present two processes for the regioselective synthesis of sucrose monoesters. The first is enzymatic, and is carried out in a medium constituted by two miscilbe solvents, namely tert-amyl alcohol and dimethylsulfoxide. The second is chemical, and is based on the use of simple basic catalysts in dimethylsulfoxide. The regioselectivity of both methdologies will be compared.
