Lipase-catalysed preparation of acyl derivatives of the germacranolide cnicin
2009
Several acyl derivatives of cnicin were obtained through lipase-catalysed acylation and alcoholysis reactions. In most reactions lipases showed a regioselective behaviour affording only one product. Longer chain acyl derivatives were prepared at lower temperature than the used in lipase-catalysed reactions, to preclude side products formation. The enzymatic approach let to prepare a family of novel acetyl and fatty acid derivatives of cnicin which are not obtainable following traditional organic synthetic procedures.

Enzyme-catalysed transformations of ent-kaurane diterpenoids
2005
Several acetyl derivatives of linearol, atractyligenin and atractylitriol were obtained through enzyme-catalysed acetylation and deacetylation reactions. In most reactions lipases showed regio- and stereoselective behaviour, allowing a family of novel compounds to be prepared. Fil: Monsalve, Leandro Nicolas.
