中文摘要	the nanocomposites formed by so3h-hollow-nanosphere and chiral amine are highly efficient catalysts for the direct asymmetric aldol reaction of cyclohexanone and 4-nitrobenzaldehyde. the catalyst showed 91% yield with 96% ee under optimized reaction conditions. the nanocomposites showed much higher reaction rate than the catalyst formed be the combination of chiral amine and so3h-mesoporous-organosilica(ribbon shaped particle with particle size of tens of micrometers)in the direct asymmetric aldol trection. this is mainly attributed to the hollow spherical morpholigy and nano-scaled partical size (16-20nm)of the so3h-hollow-nanospheres.our results show that the hollow nanosphere is an excellent catalysts or catalyst support for heterogeneous catalysis, and its applications in other fields can be expected.
