英文摘要The chirally functionalized periodic mesoporous organosilica (PMO) with C(2)-symmetric chiral building blocks, BINAP (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl), in the pore wall was successfully synthesized for the first time using a successive co-condensation and post-synthesis modification method. Chiral BINAPO (2,2'-bis(diphenylphosphinooxide)-1,1'-binaphthyl) bridging mesoporous organosilica with highly ordered 2-D hexagonal structure was first synthesized by co-condensation of (R)-5,5'-bis(3-triethoxysilylpropyl-1-ureyl)-2,2'-bis(diphenylphosphinooxide)-1,1'-binaphthy with tetramethoxylsilane in the presence of block copolymer P123 as template under weakly acidic conditions. The BINAPO in the pore wall of PMO was reduced with trichlorosilane to generate BINAP using a post-synthesis modification method. The chiral PMO with built-in BINAP (coordination with [RuCl(2)-(benzene)](2)) is an efficient solid catalyst for the asymmetric hydrogenation of beta-keto esters with ee as high as 99%, which is among the highest ever reported for the chirally functionalized PMOs in asymmetric catalysis.
