英文摘要	the pyrene-tagged cinchona quaternary ammonium salt, the chiral phase transfer catalysts (ptc-1), was synthesized and immobilized on multi-walled carbon nanotubes (mwcnts). the new catalysts (ptc-1/mwcnts) were employed in enantioselective alkylation of n-(diphenylmethyene)glycine tert-butyl ester. uv-vis absorption spectra show the effect of different organic solvents on the adsorption and desorption of ptc-1 onto and from mwcnts, respectively. the results show that 5.3 mg ptc-1 can be loaded on 10 mg mwcnts in toluene, and 0.02025 mg ptc-1 was desorbed from 12.7 mg ptc-1/mwcnts when washed by chcl3. in the enantioselective alkylation of different halohydrocarbons with n-(diphenylmethyene)glycine tert-butyl ester using ptc-1/mwcnts as a catalyst, the alkylating products were obtained with high yield and ee value. furthermore, ptc-1/mwcnts catalyst can be recovered and used repeatedly. ptc-1/mwcnts as a new catalyst is effective in enantioselective alkylation of multiple halohydrocarbon.
