CASSANI, Julia; LUNA, Héctor; NAVARRO, Arturo y CASTILLO, Edmundo. Comparative esterification of phenylpropanoids versus hydrophenylpropanoids acids catalyzed by lipase in organic solvent media. Electron. J. Biotechnol. [online]. 2007, vol.10, n.4, pp. 508-513. ISSN 0717-3458. http://dx.doi.org/10.4067/S0717-34582007000400004.
The esterification of phenylpropanoid and hydrophenylpropanoid acids, catalyzed by candida antarctica 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.
