Chiral
catalyst is an important catalyst to enhance the enantioselective reaction in order to obtain high enantiopure product. Molecular stamping technique is used to synthesize a heterogenous
Chiral mesoporous solid catalyst (CSC) through immobilization of acid active site on the surface-stamped material. A chiral surfactant (N-miristoyl-L-alanine sodium salt) that carries a hydrophobic moiety (a long chain alkyl group) and a hydrophilic amino acid group (L-alanine) was
synthesized as the template of the CSC. The CSC with various SiO2/Al2O3 ratios was synthesized via direct synthesis and post synthesis. The chiral surfactant was characterized by
FTIR and TG/DTA while the solid catalysts were characterized by means of
XRD, FTIR and TG/DTA. Characterization of CSC by using XRD and FTIR shows that the chiral mesoporous solid catalyst was successfully synthesized. The activities of the CSC catalysts will be tested in asymmetric hydrogenation of methyl pyruvate reaction. In this report, the CSC that synthesized could lead to new uses for mesoporous silica and other pore materials in, for example, catalysis and separation media, where both shape selectivity and enantioselectivity can be applied to the manufacturing of enantiomerically pure chemicals and pharmaceuticals.
