The immobilization of chiral oxazaborolidine complex in the well-ordered mesochannels of SBA-15 is demonstrated by a postsynthetic approach using 3-aminopropyltriethoxysilane as a reactive ostensibly modifier. The immobilized catalysts are characterized by a variety of techniques, such as XRD, nitrogen adsorption, HRSEM, UV/Vis diffuse reflectance spectroscopy, and FTIR spectroscopy. The catalysts are in use accustomed to for the enantioselective reduction of pungent prochiral ketones. The venture of the chiral oxazaborolidine complex immobilized SBA-15 catalysts is also compared with that of the unsullied chiral oxazaborolidine complex, which is a alike catalyst. It is institute that the vocation of the chiral complex immobilized SBA-15 heterogeneous catalyst is comparable with that of the identical catalyst <<>>
