Primary amine thioureas in asymmetric organocatalysis

, 2016
This thesis focuses on primary amine thiourea organocatalysis. The Michael addition reaction of acetone to nitrostyrene catalyzed by primary amine thioureas (PAT) was studied in detail. The synergistic effects of multiple additives (water and acetic acid) in this reaction were determined by 1H NMR spectroscopic analysis.

Novel asymmetric transformations under covalent organocatalysis

, 2018
La aminocatálisis se ha convertido en un área de gran interés especialmente para el desarrollo de reacciones químicas estereocontroladas. Esta metodología implica la condensación de aminas primarias o secundarias quirales con aldehídos o cetonas, generando cantidades subestequiométricas de intermedios tipo azometino activados (enamina o ion iminio ...
