 en Comparative esterification of phenylpropanoids versus hydrophenylpropanoids acids catalyzed by lipase in organic solvent media
Cassani, Julia; Luna, Héctor; Navarro, Arturo & Castillo, Edmundo

Abstract

The esterification of phenylpropanoid and hydrophenylpropanoid acids, catalyzed by candida antarctica check for this species in other resources lipase B (CAL-B), with several alcohols has demonstrated that the substitution pattern on the aromatic ring has a very significant influence on the reactivity of the carboxyl group due, mainly, to electronic effects, when compared to the unsaturated acids with the hydrogenated acids. It is also clear that in the saturated acids there still remain some unclear effects related to the aromatic substituents.

Keywords
CAL-B, electronic effects, esterification, lipase, phenylpropanoid acids.
