英文摘要: Heterogeneous chiral catalysis is one of the potential strategies for the synthesis of chiral chemicals. To develop high efficient and selective heterogeneous chiral catalysts is of both scientific interests and application potentials. In this review, we present the research progress of heterogeneous chiral catalysis on surfaces, in nanopores, and with emulsions and mainly focuses on the recent progresses on chiral hydrogenation, hydrogen transfer, hydroformylation, epoxidation, hydrolytic kinetics resolution, Aldol reaction, Diels-Alder reaction, enzyme catalytic reaction, etc. made in this laboratory. The chirally modified nanocatalysts can catalyze hydrogenation of alpha-ketoester with 20 000 h(-1) TOF and more than 95% cc; up to 90% ee can be obtained for the hydroformylation on chirally modified Rh nanocatalysts. Asymmetric Aldol reaction in chiral emulsion gives 99% ee and increased activity. Up to 3 X 10(5) h(-1) TOF can be achieved for emulsion hydrogen transfer. The pore effects can remarkably improve the catalytic performance for a few chiral epoxidation reactions in nanopores. An obvious cooperative activation effect was found for the hydrolytic kinetics resolution of epoxides in nanoreactors, which results in the increased catalytic activity. Several crucial factors such as catalyst assembly, pore confinement, and cooperative activation effects, which may influence the catalytic performance, are discussed.
