dc.description.abstractNanohybrid materials based on L-leucine (L-Leu) and hydrotalcites (HT) were prepared by the ion exchange and reconstruction method, under mild synthesis conditions. The location, amount and the form of the immobilized L-Leu are affected not only by the time of synthesis, but also by temperature and ultrasound treatment. The XRD results demonstrate that the immobilization occurs in either a vertical or oblique orientation with respect to the HT layers. The catalytic activity of these materials was tested in the aldol addition reaction of cyclohexanone with different aromatic aldehydes, affording mainly the syndiastereomer.. Furthermore, the present study demonstrates that both diastereo- and enantioselectivity can be easily modulated by the appropriate combination of nanohybrid catalyst, solvent and reaction time.
