Resumen/Descripción – provisto por el repositorio digital
Various bi- and polifunctional hydroxyalkanethiols were chemospecifically acylated to O-acylesters by lipase-catalyzed transesterifications in organic media. In addition, hydroxyalkanethiols with two hydroxyl groups exhibited regiospecificity or regioselectivity, depending on the nature of both the substrate and the lipase. As the chain length of the α,ω-hydroxyalkanethiol increased, the reaction was limited to smaller acyl moieties. Experimental conditions under which enzymatic acylations were carried out and their results are presented and discussed. Biocatalyzed transesterifications allowed the preparation of twenty-four new esters. The preparation of some α,ω-hydroxyalkanethiols and the mass spectra of substrates and products are also presented and discussed.Palabras clave – provistas por el repositorio digital
